In the automotive industry, TIG welding aluminum is widely used

Aluminum is a soft and ductile metal, and for this reason, it is one of the most difficult materials to weld. Especially for low thickness pieces, it is easy to make a hole if we are not very expert and do not take the correct precautions. The most common way to weld aluminum is to use MIG welding, but if you want a better aesthetic quality, it is advisable to use TIG welding aluminum.

TIG welding is considered more difficult than MIG welding; it gives you the ability to weld any metal, from steel to aluminum. It is used to weld thinner pieces and has a stronger and more resistant finish. TIG welding uses Tungsten combined with argon gas that comes out of the gun called a torch. In this case, for tig welding aluminum, argon, protects the metal from oxygen that could oxidize the parts, causing a weak weld.
TIG welding applications for aluminum
Aluminum TIG welding has many applications in the industry; in the automotive industry, it is widely to the manufacture and rep of aluminum radiators; in the bicycle industry, since the thicknesses of the tubes used for the frames and their entire structure are thin. It is also used for engine blocks, aluminum wheels for vehicle rims, and injector caps.
How to perform TIG welding aluminum?
Starting to weld, it can be noticed in the pulse that increases and decreases the amperage, and this function is necessary to keep the peace at a controlled temperature. They slowly make their way to where the joint is, while filling and moving at a constant pace to get the filling to a similar size.
With the pedal’s use, they can lower the amperage while maintaining control of the filling, since, during welding, the heat increases throughout the entire piece. The TIG welding aluminum speed has to be sustained because aluminum is a material that melts quickly; if they stay in the same place for a long time,it can damage the material creating a hole, especially with pieces of low thickness.
