Tig welding aluminum and its advantages
Tungsten inert gas (tig) is often used for high-quality precision welding purposes. In this particular process an arc is formed between the metal and the permanent non-melting tungsten electrode. With the help of the torch the gas is fed, thereby it shields the electrode and molten weld pool. In case of usage of filler material, they are added discretely to the weld pool.
There are several benefits of tig welding and it takes into consideration finer quality welds, clear-cut control of welding variables such as heat, independence of spatters and low warp. Moreover, it can be used at lower amperages for thinner metals and they can be used on exotic metals.
It can be used on different types of metals, but most commonly aluminum is used in particular metals of a smaller thickness.
Almost all types of metals can be tig welded but the most recurrent metal that is associated with this type of welding process is the aluminum, predominantly smaller thickness metals. Even though there are several other set of processes that allows joining aluminum, tig is one such process that is most applicable in the case of lighter gauges.
On the whole, as a rule, the gas tungsten arc welding process is best for repairing aluminum.
