Tig Welding Thin Aluminum Sheet

I used 1 16 1 6m 4043 rod for this outside corner joint in 040 and it worked out ok.

Tig welding thin aluminum sheet.

But that is only a guideline. Learn why mig pulsed mig tig and pulsed tig are the ideal choices when welding sheet metal. 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.

Achieving high quality welds and getting the coveted stacked dimes appearance when welding aluminum with gtaw takes practice and skill. Using too small a filler rod can be a problem too. Tig welding for sheet metal using a tig welders means that one can work on materials of 26 gauge. 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.

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.
