It is the tide of the world’s welded steel industry to apply welded steel mesh in the process of welded steel construction. Welding is not only a new type of structure material with high performance, but also a high-efficiency construction technology. Therefore, in the field of welded steel construction, welding is a fundamental shift from manual operation to factory mode and commercialization.

 

Welded steel mesh, as a new mode of steel distribution, is featured by improving project quality, simplifying construction, shortening working days, saving steels, cutting cost, etc. It is especially suitable for a big concrete construction project.

 

The prompt application and extension cold-rolled ribbed steel bars and Grade ? hot-rolled steel bars have created favorable material conditions for the development of welding net in China. The implementation of standard and regulations for safe use of welding net products has played an active role in improving the quality of products and promoting the application of welding net.

 

At present, the application of welding net in china is in the preliminary period and still has a long way to go compared with some developed Western countries. However, china has a great market potential for welding net. Some design institutes and construction units have gained a great deal of experience. Moreover, many big companies have set foot on this field. Welding net has been widely used in some areas and has yielded highly desirable results. While promoting and applying welding net, it is better to start from easy projects to hard ones and follow the sequence as floor-roof-ground-wall-road-pipeline-aqueduct-dam-airport. Meanwhile prepare for trying out the application of pole components.

 

Welded wire mesh has aesthetic values and is widely loved by people, so it possesses an admirable market. In the field of fence industry, it is common to make <a onClick=”javascript:pageTracker._trackPageview(‘/outgoing/article_exit_link’);” href=”http://www.wire-mesh-fence.net”>welded wire mesh into wire mesh fence or palisade fencing</a>. Besides that, welded wire mesh is widely used in the field of exhibition, storage and furniture, etc. For storage, the main products are archives and warehouse. While for furniture, the main products are welded wire mesh furniture and accessories of other kinds of furniture. Obviously, welded wire mesh has been more and more competitive in the market.

 

China is a large rolled steel producer in the world, however, deep and fine processing of rolled steel industry lags far behind some developed western countries, such as USA, UK, Germany and so on. Furthermore, outmoded ideas and inadequate recognition to the industry have restricted the degree of its automation. Welded steel mesh, as a new type of building material, has forged a solid step forward to China’s construction modernization and offered new and stable economic growth point of rolled steel industry. China’s metallurgy and architecture industry will surely be reformed in the following years.?

 

The development of welded steel mesh has obtained hard and soft conditions in China. Policies for promoting welded steel mesh have been successively stipulated by Ministry of Construction. Standard of welded steel mesh products and construction regulations have come into effect. Homemade GWC welding machine has sophisticated technologies and stable operations. Moreover software of welded steel mesh working design has been successfully accomplished. All of those mentioned above have laid a solid foundation for the development of welded steel mesh in China.

Over 1,000,000 workers are exposed to threatening levels of crystalline silica dust every year. More than 250 of the people in contact with these particles die with silicosis. Silicosis is a disease which has no available cure. It is avoidable if poisonous exposure levels are reduced. The most frequently used hardware for work tasks like these are fitted with an inlet intended for a portable dust collector.

Many workers must employ insufficient vacuums which can clog or don’t use dust collection equipment in the slightest. Standard vacuums that are engineered to capture dust as it is projected regularly contain the dust that’s damaging to the operator as well . A dust extractor is the option that will correctly address the need to contain dusts that may finally cause silicosis and other related breathing diseases. Most dust extractors can collect very dense levels of fine dust particles without clogging. Dust extraction is the absolute best option available to prevent the numerous respiratory conditions that can result from poisonous crystalline silica dust particles being inhaled.

Obtaining a dust extractor for all of your machines in your work area or home is essential. It prevents the risk of unsafe fine dust escaping back into the environment which you’ll be spending your time in. The average dust extractor uses a filter. The extractor pulls air to trap the dust. The dust produced by power tool use floats simply in the surrounding air under normal operating conditions exposing staff. When the dust settles an individual sometimes conducts some kind of clean-up. Dust extractors was created to help to solve the quandary of removing dust from all over the operating area of power tools.

The standard dust extractor has numerous parts which works together to clear the air of dust particles. The dust extraction hood is found close to the point where the dust is generated which is hooked up to a suction hose. The hose operates with a separation accessory to separate the dust from the air taken in via air flow. Parts used for separating the dust from suctioned air by the dust extraction system consists of filters and storms. Fans and root pumps are used sometimes too.

                                Aurora

  ‘Twas a humid but hot night…

When I touched outside

Four miles away to be precise_

After I saw a documentary

On TV

  Granules of yellow light sprayed off broken iron

As it slide across a jet of ethene_

The sight of it was pristine_

 …I strolled toward this scene:

Showers of light fragments spread out

(In unison) like stage curtains

To make way

For the faint outline of a man

Wearing a pair of gloves, and a protective mask_

Holding the welders torch…

  I relished the colors on display…

That was at large during the day

  Meanwhile,

In my neighborhood

It was unheard of

A welder working at night shift

  His section of the road_

I repeatedly overlooked_

Suddenly received my unwavering attention,

My mind floated adrift,

The experience that would follow, I guess

Would mean a lot to me…

But memory failed to remind brain

The happenings thereafter

  I was cast into the Arctic Circle

By an angel of imagination

I was filled with the spirit of science

Like the biblical john

  Transfixed into the Ireland of Patmos

The latter I must have to apply, thus

To relate my ordeal

But I am a scientist

And not a Christian

To be precise

  On the same spot

I fixed my gaze to the skies

A shimmer of lights revealed itself

To my unaided eyes

Like an open scroll

To be precise

 ‘Twas a blanket of green-blue emissions

From the elements that were likely

To hold a stake

In life beneath

  All the spectrum of white light

Made their mark

In curtain folds

Arranged in symmetry

And moving with rhythm in it

 ‘Twas strange there…

I didn’t feel cold…

The ice I stood upon felt wet (all of a sudden)

I withdrew my gaze from skyward

To the horizon

Catching sight of two sheriffs in a snow mobile

That made harness out of fuel

Closing up on me for being a wanderer…

I even forgot…

Imagination has no boundaries whatsoever

  ‘Twas weird, anyway

An African! Come to think of it…

Living side by side with Eskimo

  I returned to West Africa (on deportation)

The Niger delta to be precise

  The winds of agitation seemed to abate there

The kinsmen finally reap oil

For all their wish and toil_

But there was problem_

  The outside world was recovering

From the consequences of oil glut

…But the engineers

…Indiscriminately lit gas flares

In oil facilities scattered here and there…

Like Olympic torches telling humanity

That those activities to mark

The worlds undoing

Has begun…

In contrast, few still campaign

In favor of clean emissions

On a planet where global warming

 Had already taken its toll…

Dirty carbon and its allies… are members

Of the greenhouse family!

It’s just that they aren’t environmentally friendly;

They keep boring holes through the layer of ozone

The latter which is sunscreen

 To life on earth 

 

 

  In the light of these warnings:

Find a solution to the oil addiction…

Use it as seed…

For bio-substances which are ecologically friendly…

‘Stead of striking a match to it…

 …seems nobody listened all the while

  On a spring equinox (12noon)

Rainy season to be precise

The conflict between light and darkness

Was the reason longer night to shorter day!

Became paradox

  The sky went pitch black…

That the air was clothed in massive soot fumes

Was the reason why many babies…

Were choking to death

  The ozone depleting substances which had spoiled the ozone…

Was the reason why cancer

Drew familiar to dark skin

‘Twas chaos everywhere

A common man need not be a scientist

To deduce that white light

Meant a whole lot to life

And black light

Has no spectrum…

  Aurora lives nowhere

Save the atmosphere

Surrounding the poles

Where… the ozone above…

Have few holes

On its blanket

  Where the elements

Lining the summit of the skies

Are so clean

As to produce… lights

That eventually transformed my life forever

  Accounts rendered by arctic dwellers …

About the aurora borealis

Would make many want to flee

But… it did not even hurt

A black man like me_

Even in nightmare…

  I regained consciousness

From what turned out to be some collapse

To find myself in the hospital bed

Beside a welder

  “Please weld in my broken nerve fiber…”

I uttered loud …

“’twas a slip of tongue”

I quickly added_

…everybody in the room… burst in laughter

Welding is the most economical and efficient way to join metals permanently. Welding is very important for our economy because more than 50% of the gross national product comes from welding. There are different kinds of welding. Some processes cause sparks and others do not require extra heat. Welding can be done for various purposes outdoors, indoors and underwater, outer space.

Welders are used for various industry groups. Some of industries where welding is used is agriculture, construction, mining, bulldozers, cranes, material handling equipment, food-processing machinery, papermaking and printing equipment, textiles and office machinery.

Welding is also used in fabricated metals like pressure vessels, heat exchangers, tanks, sheet metal, prefabricated metal buildings and ornamental work. Welding is also used for transportation purpose like shipbuilding, aircraft, spacecraft, railroads, automobiles, trucks, buses, trailers and associated equipment.

Welding is also done for primary metal industries which include steel mills, iron and steel foundries, smelting and refining plants. Another group is the electrical and electronic equipment companies.

Welding is a fusion process, in which metal parts are heated to the melting point and fused together, usually with a filler of the same material melted along with the parent material. There are many types of welding processes like Oxy-acetylene Gas Welding, Arc Welding, Tungsten Inert Gas (TIG) and Metal Inert Gas (MIG).

Arc welding is mostly used for structural steel welding. Electric current that flows through a high resistance air gap generates an intense arc with temperatures ranging from 6,000 to10, 000 degrees Fahrenheit. MIG welding are mostly preferred for industrial welding applications. The two basic inert gases used for MIG are Argon and Carbon dioxide. A mixture of 75% Argon and 25% carbon dioxide is also very common.

The shielding gas that is used in TIG is Helium. This process is considered most controllable and cleanest method of welding. TIG process can weld thin, light and dissimilar materials. Soldering and Brazing are the two most common methods of joining two metals. In Soldering and brazing, parent metal is heated and the filler metal is melted into the joint where it cools. Lead based filler metals are used in soldering and brass based filler metals are used in brazing.

Uneven heating and cooling in welding operations gives rise to significant residual stresses in the vicinity of the weld. The residual stresses and discontinuities in a weld have a significant influence on the fatigue life of a part. The fatigue part of a weld is often less than the base material. Residual stresses may be removed by annealing.

Welding is not suitable for all types of metals, as some materials, such as stainless steel can get cracks when overheated. Welding has become highly automatized over the last decade, and the use of welding robots is now common place in certain industries, such as automotive manufacturing plants

Welding cast iron calls for some special procedure. Welding cast iron is a challenging task and there can be no two opinions about that. Cast iron, unlike most other steels, has much greater carbon content at 2 to 4 percent. This causes most cast iron to be brittle making it difficult to weld. If the following procedure is followed, cast iron can be welded with relative ease:

Use either cooling or heating while welding cast iron as it is important to keep cast iron out of the 150- to 500-degree F range. Preheating is widely preferred, but there are times when cooling are also done. But stick to either cooling or heating and do not attempt to change in the middle of a weld.

Though preheating the cast iron part should suffice, it is preferable to preheat the entire casting slowly and uniformly in the 500- to 1,200-degree Frange. Be very careful to heat within the stated range as overheating may cause cast iron to crack. The casting should get hot just to the extent you can to touch it comfortably with your bare hand. If need be, make short welds intermittently to avoid overheating.

Occurrences of small cracks when welding cast iron, is inevitable. You can apply some sealing compound to prevent leakages. If there are major cracks you must repair with studding. Studding is a complex process calling for a lot of skills. The first step is to drill and tap holes on the surface that has beveled. The next step is to put in steel studs and the studs should come out 5 to 6 mm above the surface and the studs should then be welded to remain in place.

Preheated welding can be easily done – particularly for small and manageable objects. While welding the cast iron without preheating, it is extremely essential the operator has good control over the welding gun and make the welds as small as possible.

Welding cast iron with an arc welder calls for different procedure. As a matter of fact, persons capable of welding cast iron with arc welder are few in number and there is a great demand for such skilled persons.

You may have to either purchase or hire a SMAW (shielded metal arc welding or stick electrode) welder depending how often you do cast iron welding with arc welder. Plug your welder into a 220V outlet and then plug in your ground cord and welder electrode holder cord into the welder. Please know that to weld cast iron, you need a special electrode. You may buy a 770 stick electrode to weld cast iron.

First of all, clean the surface area to be welded with a wire brush. Clamp the grounding clamp cord from the welder onto the piece of cast iron that has to be welded. Thereafter, place an electrode into the welder electrode holder and position the electrode near where the weld has to begin.

Continue to tap the electrode on the cast iron till an arc is created and begin to weave the electrode stick from side to side. Make it a point to keep the arc slightly away from the piece of steel you are welding. Wait for a few minutes for the weld to cool off gradually. Use the welding hammer to chip off the slag from the top of the weld.

There are about 2000 eye injuries reported everyday in US workplace. Most injuries occur due to lapses in the usage of protection gears. Flying particles are the reason for 70% of injuries that are related to eye. These injuries can be avoided hands down by wearing the right kind of protective gear required for the job. Welding is in itself a hazardous job. Welders work in an environment that is subject to arc and heat rays, slag from chipping, flying metal and dirt from grinding. Therefore it is most important to choose the protective gear that suits the work type and to wear it consistently. Tips to injuries:

Inspect your welding equipment for any damage. Keep your equipments void of rust by maintaining it properly. Proper selection of protective gear according to the type of work and intensity is very vital. Protective gears should be at reachable distance. Always make it a point to use the safety gears while handling the welding equipments. Wear the eye protection gears under your safety helmet. If your welding helmet has the auto darkening option, you can work peacefully without having to adjust the shade manually. Wearing the right shade of filter in your eye gear is very important. Welding areas are harmful place of work. They should be secluded from rest of the place of work by a curtain that can absorb welding rays. Read manufacturer’s instruction manual thoroughly. And follow the instructions religiously. Keep your cables away from other tools so that they last longer. Avoid usage of cables that are undersized, damaged or spliced. Look for advice of the manufacturer for periodic maintenance activities to be performed on your welding equipment. Keep your helmet down to minimize your chances of injuring your eye from flying particles. Always choose an eyewear that has side shields or goggles and a correct filter shade to protect your eyes. Make sure your safety eye gear meets the heat, filtering and impact requirements. Timely replacement of faulty components will aid in longevity of the equipment. If your welding work is more frequent then it is wise to go in for a welding apron or a welding jacket. Vinyl screens or transparent welding curtains can be used to keep you protected from the harmful rays. Keep your arc welding equipments well insulated to avoid shocks. The workplace should be well ventilated. This will bring in fresh air and flush out the harmful fumes or gases that arise out of work. Laser welding are extremely dangerous to your eyes. Please follow the safety instructions pertaining to the equipment meticulously.

Welding gear is famous for numerous materials in any industry. Specifically, it is utilized for the so-called combination processes like arc, resistance, laser, electron beam, stud and orbital welding. Among a list of procedures provided by used welding equipment are wave soldering and a range of brazing practices.

Welding device may operate through the aid of a welding power source. Weld controllers are also needed in order to help the methods offered by these tools. Luckily, there are also comprehensive systems with a surface or cutting machine, torch, feeders, cables, robots, positioners and feeders. Below is an explanation of arc welding purposes provided by used welding equipment.

Arc welding methods and welding equipment

Arc welding is a more general categorization for two welding forms like MIG and TIG. MIG welding stands for Metal Inert Gas Welding. Another acronym for this process is MAG or metal active gas welding. This is regarded as one of the extremely famous arc welding methods because of its flexibility. It makes use of various kinds of gas to complete the method. Several of the most general examples of these gases are pure carbon dioxide and argon gas or a blend of both.

Both latest and used welding equipment serves another welding process – the TIG. TIG stands for Tungsten Inert Gas. The procedure took its label from the actuality that tungsten is utilized when shaping an arc in between the item and the electrode. As for the inert gas portion, argon is being used. When compared to MIG Welding, this one is slower and is generally more expensive.

Arc welding has other methods included in its list. The likes of flux cored arc welding, gas metal arc welding and resistance seam welding are integrated. Other forms are spot and shielded metal arc welding.

More welding procedures served by these devices

Frictional welding adds to a list of uses served by any welding equipment. Examples are hot plate welding, plastic welding, electron beam welding and Oxyfuel welding.

Despite the diversities in these procedures, all have one thing in common. This is the essence of finding for used welding equipment that stop rust, serve varying actions and render water cooling uses. Of course a heavy-duty equipment that has engine driven generators is highly qualified to fulfill these methods.

The ZipweldersTM are considered one of the most advanced shear welder in the world today. These fully automatic welding machines were developed with an intention to reduce the operator involvement and increase mill uptime by reducing weld failures. The ZipweldersTM are designed for use on either start/stop or continuous lines like pickling lines, tube/pipe mill, coil buildup, galvanizing lines, and annealing and pickling lines. Zipwelders are used in a variety of applications such as stamping, tube/pipe mill, and many types of steel and stainless steel process lines. These machines can also be used for welding a wide range of alloys including stainless steel, carbon steel, copper, and aluminum.

The modern day RCM Zipwelders make use of some of the most advanced welding methodologies such as Tungsten Inert Gas (T.I.G.) welding, Plasma welding, Metallic Inert Gas (M.I.G.) welding, and last but no the least Laser Beam welding. The uniqueness about the Zipwelders is that they can shear and butt weld a variety of materials at varied range of thickness be it 0.15mm (.006”) to about 25mm (1.00”) and as wide as necessary. With the advent of new technology, newly developed Zipwelders machines can weld any type of weldable material, and have the capability to weld metals up to 2,400mm wide.

Another major example of innovation in ZipweldersTM is the ME 500-28 Zipwelder™. This Zipwelder is a computer operated automatic welder, equipped with an exit pinch roll. The ME 500-28 Zipwelder™ has been designed in such a manner that it can cut through a steel coil end up to 12.7mm (.500”)  thick and 700mm wide (28”) from a steel coil. When operated in automatic mode, the trailing coil end automatically stops in the shear opening, whereas the exit side guides center the strip automatically, allowing the exit weld clamp to close down automatically. The operator feeds the leading steel coil into the Zipwelder™, and then the entry sides and entry weld clamp closes. The specialty of Zipwelder™ is that it automatically shears the two coil ends, and automatically makes an MIG weld based on the selection as per the on-board computer which controls not just the weld gap, wire speed, weld speed, but also the welding voltage. As with shear welder, these ZipweldersTM can be similarly custom designed, as per the requirement of the customer.

Did you know that there are many different kinds of welding jobs and types of welding technologies? The best welders, and the ones who make the most money, are the ones who are well trained in many different types of welding technologies.

MIG Welding

For instance, there is a big difference between MIG Welding and TIG Welding. MIG or “Metal Inert Gas” welding involves the welding gun forming an inert gas shield over the flux to keep atmospheric elements like hydrogen from corrupting the weld. It’s usually used in a shop or areas protected from the elements. MIG welding is considered a standard practice that anyone who got decent welding training would know how to do.

TIG Welding

TIG Welding is a different matter. Tungsten Inert Gas Welding commonly known as TIG, utilizes only one gas-Tungsten-to protect the weld. It’s used to welding a variety of metals that MIG welding can’t handle, such as Magnesium, Aluminum and Stainless Steel. More specialized welding training and welding technology courses provide specialized TIG welding instruction. Because of its difficulty, those who have extensive TIG welding abilities typically get paid a lot more than those without.

Both TIG and MIG welding technologies are Arc Welding techniques. By getting the best welding training, you can earn more money doing complicated TIG welds and MIG welds. There are plenty of quality vocational courses in Oklahoma that will provide the needed training that will help you get your foot in the door.

Learning the Cutting Edge Welding Techniques is a Great Way to Start Your Career

Having several months of welding training and education under your belt when you go into the workforce is a huge advantage in a field that is still populated by many who have simply picked up the skills along the way. Since the success of your welding career is due almost entirely to how much you know and how well you do your work, this preliminary education in core welding skills is invaluable. You can get your Oklahoma welding associates degree from several schools in Oklahoma, and the same skills and certifications that you gain will help you even if you move on to other states.
