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.

So What Are Some of the Applications For the Gas Tungsten Arc Welding Process?

By: Jennifer Jenkins
Posted: Jan 04, 2011

So what are some of the applications for GTAW?
Obviously, this process is used for a wide variety of applications where the parts are made out of non-ferrous metals. Maintenance and repair is done by both manual and automatic methods of Gas Tungsten Arc Welding. From stainless to titanium, aluminum, inconel, monel, cobalt, magnesium, hastalloy, you name it, and it can probobly be welded with TIG.

It is appropriate for welding of pipe and tubing in all positions. The excellent control of heat input gives maximum penetration while preventing melt-through on the root (first) pass. A lot of times a procedure is used where the root pass is welded with the GTAW process and then completed with Shielded Metal Arc Welding, Gas Metal Arc Welding, or flux Cored Arc Welding. This is used to obtain a high quality, low cost weld.

Consumable inserts are sometimes used in critical service applications. These inserts reduce porosity when alloyed with deoxidizers, improve the contour of the underside of the weld, and minimize cracking in the weld. On thin pipewall (depending on the base metal) , complete fusion is obtained without the use of filler metal. Filler metal , is used with thicker sections in order to fill the joint. Pulsed current may also be used.
Automatic circumferential or orbital Gas Tungsten Arc Welding is also used to weld pipe and tube.
Power piping, Air piping, Refrigeration piping, Chemical industry process piping, and Nuclear power piping are some of the different industries that apply the Gas Tungsten Arc Welding  process for welding pipe and tubing. Vacuum jacketed piping and pressure piping are a couple of cases where critical welding is required.

Nuclear Power Facilities :

Critical welding in the construction and repair of nuclear power facilities is required. Both manual and automatic methods are employed for many nuclear applications because of their precise control of the welding.
Pressure Vessels, Boilers, and Heat Exchangers :
Gas Tungsten Arc Welding has a wide range of applications in  the pipe and tube industry for the welding of pressure vessels, boilers, and heat exchangers. It is employed where full fusion welding is made from one side, without the use of permanent backing rings, and on girth butt welds with a smooth internal contour. Adequate mechanical strength and corrosion resistance for a particular service encountered can be obtained by choosing the correct filler metal and welding conditions.

Aerospace :

The Gas Tungsten Arc Welding process is the major welding process used in the aerospace industry. Aircraft, spacecraft, and launch vehicles are a few of what’s included in this industry. Some of the metals welded include aluminum, nickel, stainless steel, magnesium, and super alloys. Both the manual and automatic methods are employed in this industry. Pulsed current is also used extensively in this industry. Just about all critical welds made in this industry are done by TIG and a highly skilled welder.

Ships :

The Gas Tungsten Arc Welding process is applied in the ship-building industry because different materials like aluminum, molybdenum, and stainless steel are used. There is a lot of applications in this industry for the welding of stainless steel and aluminum.

Transportation :

The Gas Tungsten Arc Welding process is used somewhat in the automotive and railroad industries. It is used mainly for the welding of non-ferrous metals, maintenance, and for small components. Fabrication of aluminum fuel tanks is one application used in this industry.
In the railroad industry, several of the interior components are made of aluminum, stainless steel, monel, and copper are sometimes welded by this process. Some maintenance and repair of passenger trains is also performed.

Another area of use for this process is contractor work. If you have the equipment and skill you can charge anywhere from – 5 per hour. I personally know a person who’s company charges per hour for TIG aluminum jobs and he gets it. If you don’t have the equipment, you could always try to go to work for a contractor. TIG welding is a very rewarding profession, and they always need skilled welders.

So my advice to you is, if you want to be a TIG welder, get some training ( I recommend The Hobart Institute of Welding Technology in Troy, Ohio ) They’re the best! Maybe, if you could afford it,  get a certification in GTAW while you go to school there. Apply yourself, and learn as much as you can. Then be aggressive, and go out there and get a job in the TIG welding industry. Make sure to keep your attendance perfect, if at all possible. Employers want you to come to work and be on time. If you do this you’ll be on your way to an interesting and fun career that is rewarding.

Welders are used when there is shortage in electric power supply. Various types of Welders are used. Engine-driven welders are very popular of the genre. This type of systems is used for outdoor applications. But engine-driven welders are designed in such a way so that it can be used for indoor applications. At times when there is problem in supplying power to electric (plug-in) welders, this type of technology is used. These indoor circumstances include everything from major plant shutdowns to minor repair jobs. It is better to use the engine-driven welders in a large space that has good ventilation. There are some basic things that need to be taken into considerations while selecting an engine-driven welder. These include:

1. Application- First of all you have to consider this factor. You have to define the application and then select the welding process.

2. Engine Type – It is one of the most important issues that you need to look at after defining the application. Before you take any definite decision ad select the welder, it is better on your part to check the engine type. It is truly one of the most crucial steps that you need to take. LPG (liquid propane gas), gasoline or diesels are the main options. You can get better fuel economy with the diesel engine option compared to the gasoline engine. Another positive side of diesel fuel is that it does not catch fire as easily as the gasoline. Refineries prefer to select diesel-fueled machines over gasoline fueled machines. Another important thing to consider is whether or not the fuel is supplied at the site. Diesel is the common choice. But the decision is taken on the cost saving factors. There is a great thing about the gasoline. I cold weather situations, gasoline engines are preferred. They take less time to start compared to other fuel options. They work without the aid of extra starting equipments, such as winterized fuel or ether start kits. LPG is another fuel option but it is not so popular. It is selected only when there is no gasoline or diesel. It is also used in case the other two options are not allowed for indoor applications.

3. Portability is another very crucial issue that is considered while selecting a welder. There are many areas where taking large welders can be a big issue. In such cases, easily portable welders are a great option.

So make sure you exercise your discretion and select a welder as per your needs and requirements.

Welding is a sculptural process where it deals with raw items such as metal and pipes Historical monuments, construction of building, bridges, ship building, automobile, aerospace, power plants, refineries and lots of manufacturing activities needs the process of welding and it is a part of it. The manufacturing industry came to know about the importance of welding service during 20th century and new welding equipment with latest welding technology were introduced later and requirement for welding supplies increased a lot. The welding industry should be equipped with modern tools such as welding electrodes, welding torches, welding consumables and welding guns and should follow the proper welding system with appropriate welding technology.

There are different types of welding process and each one has its own merits and demerits. Arc welding is a welding technique that uses a welding power supply and creates electric arc between electrode and base materials and Forge welding is a process that joins metal by heating them to high temperature. Tig welding uses tungsten electrode to produce the weld and it is the other name for gas tungsten metal arc welding and it is used to weld thin sections of stainless steel and non ferrous metals. Mig welding is an automatic arc welding process preferred for its versatility and speed and weld aluminum and non ferrous materials. Spot welding is a process in which metal surfaces are joined by the heat obtained from resistance of current flow. Gas welding is also called as oxy-fuel welding and use gases to weld and cut metals. Stick welding or shielded metal arc welding is a manual arc welding process that uses consumable electrodes. Plasma arc welding uses plasma gas and has narrow penetration with greater energy concentration.

Plasma arc cutting is an easy process if you follow these safety precautions. Do not touch any wet surface when operating the plasma cutter equipment and don’t use plasma cutters without any proper protection. Don’t remove the ground cable, which is attached with the work object and ensure that there is proper earth since it connects with high electric circuit. In welding, electrode is used to conduct current and it is of two types such as consumable one and a non consumable one. Shielded metal arc, gas metal arc, flux cored arc and submerged arc welding comes under the category of consumable electrode methods and tig welding and plasma arc welding are non consumable electrode methods

Apart from the welding products such as mig, tig, stick and submerged arc welding products, the other products such as wire feeders, spot welders, multi process units and water coolers comes under the welding products. Welding equipment is a heat generating equipment and it is needed to be cooled by some machines. Water coolers are the instruments which prevent overheating of machines. These have the motors which create a flow of water and cool the welding equipment. Tungsten electrodes are used in tungsten arc welding process. Tungsten electrode is used to weld stainless steel and non ferrous metals and it is called as a steel electrode.

I am planning on replacing my 12 inch exhaust tips with some 16 inch..
How much will it cost to remove the 12 inch and weld in the 16 inch.?

I already have the 16 inch tips so I am looking for the price of labor only.

Thank you

Cheap and easy way to start welding. Less than 100 bucks!

I mean except for being underwater ,are the other kinds of welding different in the amounts of physical exertion . Also do you think someone who is not very strong- physical person can do some of this work ?
