Tig Welding Thin Aluminium Sheet

However welding aluminum presents some challenges from controlling heat input to dealing with the oxide layer.

Tig welding thin aluminium sheet.

Using too small a filler rod can be a problem too. Gas tungsten arc welding gtaw has traditionally been considered the go to process for welding aluminum because of the high weld integrity and aesthetic appearance the process provides. But that is only a guideline. I used 1 16 1 6m 4043 rod for this outside corner joint in 040 and it worked out ok.

Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges. Using this process enables more than effective work on thin materials as it provides high precision and high quality work. Another rule of thumb for tig welding sheet metal thicknesses is try not to use a filler rod that is thicker than the metal you are welding. Tig welding for sheet metal using a tig welders means that one can work on materials of 26 gauge.
