Pipe welding is no easy task.After all, you are usually using it to join very large pieces of metal or plastic together–sometimes, so that very powerful chemicals and gases can pass through them.However, pipe welding is an incredibly popular way to manufacture things because it is the most cost-effective way to join pipes together.It can be done for a variety of projects, both big and small.

If you want to become a pipe welding pro, you will have to start by understanding the ins and outs of some of the basics, like:

1.Butt welding

If you need to join two piece of metal or plastic together, than you need to know about butt welding.In fact, butt welding has become a popular welding process because it is easy to do and it rarely requires any kind of post-welding work like other welding techniques do.

During this process, the two pieces are laid side-by-side and welded along a single seam.If your butt welding is done correctly, you will never see a seam, and you will never see any type of brittleness or corrosion develop.  Instead, it will just look like these two pieces naturally fit together!

2.CNC machining equipment

An abbreviation for “computer numerical control”, CNC machining equipment is vital to the pipe welding world.This equipment can be pre-programmed with a computer to do the work, instead of having an actual human being do it.CNC machining equipment can work faster than a person can, and it can simulate all of the movements that a human can make –by being able to move machines, equipment, and tools in virtually every direction.

As an added benefit, CNC machining equipment it never gets tired, like an actual person does.In fact, these machines can run 24/7 if you need them to! They will literally keep running until you tell them to stop.

3.High pressure fittings

Available in virtually any variety – from elbows, to couplings, to crosses, to tees, to filters – high pressure fittings are another important part of pipe welding.

By having fittings that can easily adapt to very high amounts of pressure, you can rest easy knowing that they will be able to hold their own against fast-moving fluids, oils, and chemicals.When you have weaker fittings, flowing fluids can break them down– leading to leaks and spills.  Instead, high pressure fittings can be used to connect pipes together in all sorts of situations.

Lets not kid ourselves; a welders job aint fun! A welders got to work in the hottest and sometimes in the most cramped up space as he brings to life the most complicated of designs. But if its so much of hard work, why is it that more and more people would rather prefer to face the dirt and grit than anything else? The job satisfaction thats achieved at the end of the long and grueling work is incomparable. A design thats finished to perfection is nothing less than a master piece. Thanks to technology, the work isnt as grueling as it was a few years ago.

Welding is a huge field, with plenty of specializations. One such is, mobile welding. The job allows people with their own vehicle to undertake welding jobs on the go. The welding vehicle is modified to accommodate the equipments used for the service. While most welders perform structural welding or pipeline welding, the most common among them is stick welding.

Some of the most common service offered by welding companies includes fabrication, welding and cutting including TIG, MIG, residential, industrial and even ARC gouging.

When choosing a professional for mobile welding, remember to exercise care and caution. The greatest advantage of seeking help from a professional mobile welder is that you can get the best help right to your doorstep rather than having to scout for them. The expert can come to your place to weld your fence or steel structure rather than you going to him for help. Albeit a little expensive than normal services, mobile welding has become very popular mainly because of the convenience aspect.

The internet is a great resource to look for qualified welders in your place. You can choose them from the several web directories in your place. But make sure, you enquired well about his credentials. Theres nothing quite disheartening than a product that is shoddy. Another thing to look for in a mobile welding service company is if they are registered with an association for welders in your locality. Professionals hired through these associations are sure to follow industry set standards.

Its not only the mobile welding industry, but the entire welding industry in general has witnessed stupendous growth. If reports from the American Welding Society are to be believed, for every two welders who retire, only one enters the workforce. This automatically translated business for the people joining the industry.

So the next time youre looking for the convenience of getting your work done at your place, make sure you call for the services of a professional mobile welder.

Welding is the sculpturing process of joining materials, including the likes of metals and thermoplastics through coalescence. Work pieces are melted and filter material stuffed in between to form a pool of molten material, which eventually cools down and becomes a very strong and robust joint. Welding equipment is used to carry out this arduous task. There are a lot of sources that can be used for welding such as gas flame, electric arc, electron beam, friction, ultrasound and laser.

Welding supplies and welding equipment have a big role to play in welding. The personnel overseeing the process and being involved in it directly make use of these available machines to ensure a smooth process. The welders who do the job in a variety of environments such as open air, underwater, outer space etc. make it a point to carry these with them to ensure successful completion of adjoining two metals.

There are multiple forms of welding equipment. Manual methods include the likes of shielded metal arc welding. There are semi-automatic processes including gas metal arc welding, flux cored arc welding, submerged arc welding and electro slag welding. Laser beams have also been used as welding equipment with the laser beam welding process being a highly sought after service. Robot welding is the latest process to have been embraced with its popularity reaching out to industrial settings.

One of the latest additions to have been made to welding equipment and welding supplies is the MIG Welder. It happens to be a high tech machine with lots of controls and the welding clamp attached to a wire which is further connected to the machine. The MIG Welder offers a certain degree of advantage over others because of its ability to swing the deal and weld metals without much struggle and toil.

Welding equipment and welding supplies make the job of adjoining the two metals a very easy one. The metals have to be melted first, a fiber being inserted into the picture for the molten amalgamation to join and solidify after cooling down. This process is usually carried out through various devices and they all have their own special importance.

One of those things about the products and the Welding equipment is they make the process of metal welding real effortless. The metal melting process happens quite smoothly and the welding supplies help out with fiber insertion. That too happens without a fuss and after that, the amalgamation is left to cool down before the metals finally conjoin and become a single entity.

These products are very delicate and have to be handled quite precariously. Mishandling and mismanagement makes way for chances of some sparking. That has to be averted, and it is usually advised that the machines should be switched off at once when the usage is over.

Most of the ones that can be seen in workshops and other outfits are the ones operated through electricity. However, others find their usage in their own given place.

A torch lighter usually refers to a butane torch or propane torch used to light the flammable gases butane and propane respectively. Be it for smokers or for campers, here are some tips about torch lighters in general.

Propane or Butane torch lighter—which one to pick?

Both the gases are similar in characteristic, but when it boils down to efficiency, butane wins hands down. This literally means that for the same quantity of gas, butane would provide more energy than propane. Additionally, butane is also available at a cheaper price than propane. Unfortunately, unlike propane, butane tends to freeze up as soon as the temperature drops below 0°C and it cannot be handled by being shaken around.

These limitations can prove disadvantageous, if you are a camper with a backpack and if you wish to hike in the cold outdoors. This is one reason why campers and hikers prefer propane torch lighters to the butane alternative, but it does not make much of a difference to smokers in moderate climates. Propane is definitely capable of handling more rough treatment than butane, but if you are using a torch lighter in a place where the temperature is on the higher side, then there is no reason to opt for the latter. In addition, in today’s market, special butane torch lighters are available, which can achieve higher temperature much quicker than the traditional ones. This is good for campers and smokers both, since they have no need to hold the flame for a very long time to light the fire.

Torch lighters can help fix simple home hardware problems—unbelievable but true! You must have come across daily problems at home, wherein you have found it difficult and sometimes impossible to loosen the stray stubborn nut or bolt. Greasing or hammering also doesn’t seem to help sometimes. This is because of the natural weld because of years of corrosion and it could hold up your work for hours. However, one of the best ways to deal with these simple home problems is to use heat.

A regular lighter will not help, but you do not need to call in professionals for the same —just use a propane torch lighter. If you use it indoors, ensure plenty of ventilation. In addition, do not fret about the cost. There are mini propane torches available for household use, which could be just what you are looking for.

Finally, traveling with torch lighters and matches can be cumbersome, especially in airplanes. Most liquid-filled lighters or disposable butane lighters are all right for plane travel, but cannot be checked in. Torch lighters are disallowed completely. Used by many pipe smokers, it can create a needle-like flame capable of being reaching up to 1370°C — much hotter and more intense than the less malevolent cigarette lighter.

Before analyzing the existing wage structure of people welding jobs or assessing what salary the welding jobs merit, it will be sane to first study the job profile of people who are professional welding operators.

Simply stated, welding is the process of heating and melting metal parts to permanently join them. Welding finds wide applications in many industries including automobiles, airplanes, ships, and fabrication of sheet-metal products. Welding also becomes necessary when constructing bridges and building products. It is also the part of a welder’s job to cut metal into pieces or to cut structures as per design and to discarded unwanted metal.

Welders are mostly classified as skilled workmen as welding jobs do call for some special training and expertise. Professionally qualified and experienced welders work from blueprints and to other pre-determined specifications. They are fully aware of the welding properties of various kinds of metals and the varying techniques needed to weld them.

In fact, with the availability of advanced technologies, welders even rely on computers and robots to weld metal pieces to precision. Less skilled welders work on projects that do not call for advanced skills like common types of fabrication and do repetitive work in manufacturing units that calls for no special knowledge of welding properties.

There are numerous methods of welding that use either electricity or various gasses to generate the required levels of heat to bond metals. Arc welding, which can be done either manually or with the aid of machine, is the most common method. Another form of welding, that is equally common, is the use of gas. Though many types of gases are deployed, the common one is an acetylene and oxygen torch.

As regards the educational qualifications required to pursue a career in welding, a high school diploma with mathematics, physics, mechanical drawing and principles of electricity will be useful – though this qualification can not be deemed essential. It can also be said that a basic knowledge of computer and functioning of robots will be helpful for advancing in one’s career as a welder.

Industrial training institutes, vocational trade schools, and some community colleges offer training programs for welders, and some manufacturing companies also provide in-house apprenticeship for welders. Apart from the educational qualifications and professional training, an aspiring welder should possess sound health, manual dexterity, sharp eyesight, and good hand-eye coordination.

As regards wages, the currently prevailing standard norms are:
* Hourly Rate      .40 – .41        
* Overtime     .79 – .26

There are employers who also offer:    
* Bonus     8.73 – ,511     
* Profit Sharing     6.27 – ,057     

There could also be earnings in the form of tips, commissions and cash incentives.  Of courses the salary/wages will vary depending on the location and the size of the employer.

Underwater welders and those who well-qualified and adequately experienced in complicated forms of welding and those who inspect welds, or teach welding earn more money than people who do routine welding jobs.

Construction companies and manufacturing plants offer ample employment opportunities for welders. Local union offices or state employment agencies offer guidance about training and job openings for welders. Newspaper classified ads and Internet job banks are also excellent sources of information for people wishing to embark on a welding career.

When you cut, bend, or assemble metal materials then you have what is known as Fabcrications. The end result is usually formed out of sheet metal or structural steel. You might be familiar with the terms blacksmithing, boiler making or iron working which are the professions that use structural steel fabrications.

Fabricators begin creating their product by cutting the material using a combination of chiselling, shearing, or sawing techniques, a CNC cutter, or a handheld torch. Next, the fabricator will bend the material using a hammer or press brake. After the bending is complete, the fabricator will join the pieces of material together using welding techniques, riveting, fasteners, additional bending, or binding with adhesives. The fabrication processes usually involves a combination automation and human labour.

Developing the frames used in high rises and commercial buildings

Structural steel fabrication is a process often employed in the making of steel frames, which are used in building. Many buildings are constructed from a skeleton frame made of horizontal I-beams and vertical steel columns. These steel frames are positioned into a rectangular grid that will support the roof, walls, and floors of the building. This technique is used to form all sorts of structures, including skyscrapers.

High strength with the benefit of aesthetic appeal

Steel fabrications can be used on both residential and commercial construction products. The steel columns and beams are both durable and cost-effective for forming the frame of a building. The steel framing provides a high strength, sustainable structure with an added benefit of aesthetic appeal.

Using structural steel fabrications in constructing buildings allows for quick design and erection to get your building up and running as soon as possible. In addition, the materials and services required are readily available. Structural steel fabrications allow for more designer freedom as well.

Benefits of using structural steel fabrications

If you are planning to construct a building, either residential or commercial in nature, consider the use of steel fabrications in your project. There are a multitude of benefits associated with these building materials including durability, an appealing aesthetic and greater design freedom. In addition, the materials and services you need to complete the project are affordable and readily available.

Should you decide to employ fabrication and/or steel framing in your next building project, you are well advised to find someone with a good deal of experience and knowledge in the industry. You should look for someone with a good reputation for quality steel framing and construction. Though price is important, it should never be more important than quality. When you find the list of companies to call, be sure to ask about their previous steel fabrication experience and their recent jobs completed. The professional companies will be happy to answer your questions and highlight the various jobs that have recently completed.

Then you will be able to choose the company that can best serve your construction needs. Steel framing is one of the best construction options available for new buildings, especially large ones. The material is durable and easy to work with, and there are no limits to the designs that can be created. There is no doubt that if you use structural steel framing you will get a great result for your job.

Flux Cored Welding is not a “new” process, being dated back to the 1920′s. Instead of having the protective/stabilizing flux on the outside of the wire, as in “stick” rods, it is at the core of the wire. This flux does the same job as do the gases used Gas MIG Welding.

At Weyerhaeuser Timber Company, we periodically built rail-car “car sills”. These are the heavy metal frames upon which the railroad boxcar sits. We would use a “pantograph” machine for semi-automatically cutting out parts for the sill. Then we’d weld many of the parts with “jet rod” (7024 type), which is super easy to run on flat welds. The welds looked VERY nice.

For most other welding, we used heavy duty MIG welders. We’d fiddle with “gas” settings & wire speeds till it was just right. Then we’d just go & go till we got to the end of the pieces. We never had to worry about “duty cycle”, we just kept going. We could get a LOT done with those MIGS. If you are going to do a LOT of welding, you may want to start with a wire feed welder.

I prefer a flux cored welder because there’s no “gas” bottles nor pressure adjusting, nor are there issues with welding outside in the wind. It’s a personal decision; gas or flux cored. I would use the recommended setting ranges, running on the “hotter” side just to get the feel and coordination of running beads. An in-expensive, occasional use flux cored machine for the little jobs is fine. For my bigger jobs I go to my stick welder.

More tips and ideas for flux cored welding:
* If you go through eBay to but one, you may want to first go to welding supply shops & see them in person.
* Flux cored welders are mainly for the thinner materials. If you’re going to work on cars & the like, you would probably prefer wire feed over stick.
* I’ve done a lot of sheet-metal work with stick rods, but I needed to use really small rods, plus do a lot of “touch & go” welding, rather then continuous welds.
* One of your first accessories should be a pair of “MIG pliers”. They are great for helping you keep your equipment clean & to be able to easily convert to other wire sizes.
* When you install your 1st wire spool, don’t mess with bending it around much, or it may break. Re-threading & pulling out any that’s already in the guide tube can be a pain.
* Again, use recommended settings, then make adjustments as needed. Some machines are really limited for adjustments, so you may have to experiment with your gun positioning & arc length.
* I’d bet that there are as many variations for adjustments as there are different manufacturers & models. Be patient & keep trying.

Machine Selection:
* This is primarily dependent on your budget, then on exactly what type of welding you’ll be doing. If you feel that you might go beyond just doing your own thing, then get the best you can afford.
* The cheaper units are all pretty much the same: for light duty at home projects. The mid-priced ones can get you started in your business, but you’ll likely be up-grading as soon as you can afford to.

Flux Cored Troubleshooting:
* Don’t let go of the wire end when you’re loading a new spool! It may not feed right even if you can get it all un-raveled & fed through.
* If you feel the wire pushing against the bottom of the puddle, turn the speed down or the heat up (or both).
* Try not to keep the nozzle end too close to the puddle. That can make more splatter get into the tip piece.
* When you first start the weld, stay put momentarily to allow the puddle to form & fill the initial crater.
* Uneven feeding? Make sure the wire guide isn’t twisted or kinked.
* Can’t see an actual puddle? Clean you helmet lens & get closer. If all you’re seeing is a bunch of sparks, you’re not really seeing what’s going on. And again, you need to go at a speed that gives enough time for a puddle to form.

Moreover we will see now the various types of welding machine and its types in brief. Firstly, we will discuss about plasma cutters. This process is also known as child of modern invention, this process also uses science in there process.

It also uses the plasma gas and perform multi task of cutting and welding. Totally in market there are nine plasma cutters and five of them are listed as super cut fifty super cut sixty, super cut forty, super cut fifty, power plasma 50 power plasma sixty and power plasma 70 and also power plasma 100, power plasma 80, plasma machines is also available for processing.

Five types of the TIG welders are power I TIG -200 power TIG 200 DX, power TIG 250 EX power TIG EX power TIG 225 LX power TIG 315 DX.

TIG welders are of five types which is easily available. They are power I TIG -200 power TIG 200 DX,  power TIG 250 EX  power TIG EX  power TIG 225 LX  power  TIG 315 DX . The starting minimum voltage required to start the unit is 220/240v it can also afford consistence and stable parameters with the standard feature being with foot pedal control.

There are machines which comes with the advantage and special features like arc force control, spool gun capability, digital display, consumer low power and many more which is specially designed so that these machine can be used in all industrial purposes and serve all industrial process, such machines are easily available and are called  MIG machines.

They are namely I MIG 205, I MIG 160, I MIG 250, and I MIG 200. They are different types of MIG machines available for various uses. The power arc welder is also known or commonly known as stick welders. They are two types of stick welding machines available they are power arc 200 and power arc 160. These machines give good competition and lead the industry with their performance and the price too. It also gives the benefit of excellent arc characteristic.

So when talking about welding process, the welders have various options in different type of welding machine and the welder or the user can weld ant type of metal easily and can be satisfied with a smooth welding characteristic with a high duty cycles. Enjoying the benefits of the machine can be fullest only if u select a machine which is best suits your work.

Why has my MIG wire gone bad all of a sudden?

“I’ve been using this MIG wire for the last six months without a problem”. “Now after having used many spools the wire its gone bad”. “What’s happened?

Sound familiar? The trouble here is that the person or company that you bought your MIG wire from cannot guarantee you quality.

Did you buy the cheapest stuff you could find? Ha-ha…As the saying goes, “he who buys on price, and price only, gets what he paid for”.

Sounds harsh but that’s the truth. Quite often you find end users happily welding away with their current brand of MIG wire. When all of a sudden they go and open up the next new pallet of wire that just arrived, slap it on the machine and the welds are all over the place.

Spatter, burn backs wire not feeding properly and so. What’s going on, they think to themselves. “Ahh, I know, it must be a worn contact tip”. So off they go and replace the contact tip with a new one. But no, sure enough same problem. “Well, it’s been a while since I change the liner”. So off they go and do that. Yet sure enough the same problem is still there.

They think to themselves, “well I’ve changes everything else, it can’t be the wire. It’s brand new and I’ve been using it for over six months without any trouble”.

This is such a common thing to come across in the welding industry, and it affects everyone throughout the world. Whether you’re in the USA, Australia, New Zealand…anywhere.

So what is it, what’s the problem?

The problem is quality.

The person who is supplying your wire can not guarantee you quality. But you think to yourself, it can’t be the wire, no way. I’ve been using this (xxxx) brand wire for ages. They are a huge massive company, they sell MIG’s, TIG’s all sorts of welding gear no way can it be the wire that’s giving me problems….can it?

The trouble is that unless you are guaranteed the quality of you welding wire your “up a creek without a paddle”, so to speak.

With so many people selling welding wire these days it is extremely hard to come by a quality wire. The majority of goods made in the world today come from China or India. With huge populations and low wages, they are the cheapest places to buy things from.

There are over three hundred manufacturers of welding wire in China alone. What does this mean to the quality of your MIG wire?

This means that if the brand of wire on the box is (xxxx) they are not the manufacture of it. You need to ask the sales person….ARE YOU THE MANUFACTURER OF THIS WIRE?

Because what happens behind the scenes is the company you bought the wire from has a big argument with their supplier in China or where ever. And they say stuff ya….well go next door and buy from them. Hey with over 300 manufacturers in China alone they can pick and choose who they like.

So they change their manufacturing supplier, and this happens all the time. But when they change manufacturer the quality also changes. That’s why your wire has gone bad. And that’s why they can’t guarantee you the quality.

Simple as that.

Each time they change their manufacturing supplier the quality changes as well. There is a huge difference in quality of wires.

Okay so what do I do now, which wire do I buy?

The secret is to buy a wire that is supported by the manufacturer. You need a manufacturer that has been producing quality welding wires for years and years so that they have the art perfected.

Did you know that there are general “quality” mig weldng wires and precision MIG wires? Which type of wire do you think that the big boys use? When I say that I mean vehicle manufacturers, earth moving manufacturers and so on, companies that use it by the tonne. What do you think they are after in a welding wire?

They are after:

o Precision o Reliability o Repeatability o Consistency o Quality o Accuracy

How much money would Toyota or Mitsubishi or Caterpillar lose per minute if a welding machine was down? I sure bet it would be an awful, awful lot of money. These manufactures don’t want a single welding machine in an assembly line to break down. Cause if one thing stops, the whole show stops.
