The acceptance of new equipment has been researched and appears to be welcomed consideration to the current customer base. Continual product development will ensure balanced growth and recognition as a source of expertise in welding equipment and processes. Now you may think talking about gas before the welder is odd, but bear in mind that if you are on a budget then the gas is going to represent a significant outlay.
The tungsten is the electrode that sticks out of the front of the torch. Confusingly there are various different types, that are better suited to different applications.
Your welder may come supplied as mine did with an unsuitable tungsten electrode. To avoid damaging the electrode, you will need to hold it around 2 — 3mm from the working surface. With a welding mask on this is no mean feat, and will take a great deal of practice to get the hang of. Welding for Dummies. Download e-Book.
Posted on. Page Count. Steven Robert Farnsworth,. Get the know-how to weld like a pro Being a skilled welder is a hot commodity in today's job market, as well as a handy talent for industrious do-it-yourself repairpersons and hobbyists. TIG welding is a commonly used high quality welding process.
TIG welding has become a popular choice of welding processes when high quality, precision welding is required. In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately. Tungsten inert gas TIG welding is the process of blending together reactive metals such as magnesium and aluminum. The TIG welding method became popular and useful in the early s and, as a result, has greatly propelled the use of aluminum for welding and structural processes.
TIG welding is commonly used for both high quality and manual welding. During the process of TIG welding, an arc is formed between a pointed tungsten electrode and the area to be welded.
As a result of the gas shield, a clean weld is formed. This prevents oxidization from occurring. The type of gas shielding typically used for TIG welding is argon, helium, or a combination of both. When combined, these two gases can ensure a higher welding speed and welding penetration.
Argon is the preference of most welders when it comes to TIG welding. It is often used simply because it is heavier than air and provides better coverage when welding. With TIG welding, one can perform a variety of weld types on several different metals. Steel and aluminum, however, are the two most widely used metals. The filler rod is another important aspect of TIG welding. Usually made from the same material as the base metal, it is used for reinforcing joints and welding heavy metals.
GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques.
