Tungsten inert gas (TIG) welding is the technique of combining together reactive metals, for instance magnesium and aluminum. Through the welding procedure, an arc is created between a pointed tungsten electrode and of course the area to be welded. A shielding gas is used in order to help produce a clean weld, as it helps prevent oxidization from happening. The welding technique grew to become common and valuable back in the early 1940s and, as a result, has tremendously propelled the use of aluminum for welding and structural procedures. It can be widely used for both excellent quality and manual welding.
The kind of gas shielding generally used for TIG welding is argon, helium, or possibly a mixture of both. When incorporated, both of these gases can certainly ensure a better welding speed and welding penetration. Argon is often favored by most welders merely because it is heavier than air and offers much better coverage when welding.
By using the TIG welding procedure, any individual is capable of doing many different weld types on a range of different metals, however steel and aluminum are the most favored. A filler rod, typically made from precisely the same material as the base metal, is used for strengthening joints and welding heavy metals.
