Tig Welding Thin Aluminium Sheet

When welding thin metal the main objective is to avoid warping burn through and excessive heat affected zones while still ensuring the weld has enough mechanical strength for the application.

Tig welding thin aluminium sheet.

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. Learn why mig pulsed mig tig and pulsed tig are the ideal choices when welding sheet metal. Using too small a filler rod can be a problem too.

However welding aluminum presents some challenges from controlling heat input to dealing with the oxide layer. 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. Using this process enables more than effective work on thin materials as it provides high precision and high quality work. Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges.
