Tig thin sheet metal welding.

Tigging thin sheet metal miller welding discussion forums 1. 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. Try welding with a scrap sheet metal piece and practice many times until you start working on more important projects. Tigging thin sheet metal 11 30 2006 01 51 pm.

The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten. Tig welding for sheet metal using a tig welders means that one can work on materials of 26 gauge. Short circuit transfer mig short arc tig and pulsed tig welding processes provide the most control over the heat to address these challenges. Because it will have you a lot more control over the whole process and it is more forgiving in case you do anything wrong.

In this video i weld 1mm thick steel with my tig welder. Using this process enables more than effective work on thin materials as it provides high precision and high quality work. Titanium always requires shielding the backside of the weld to prevent oxidation. Was trying to butt weld but it kept burning the edges away before fusion took place.

I am new to welding and am trying to butt weld 22 guage mild steel sheet together i am using a miller dynasty 200 dx tig tried 1 8 ceriated electrode 3 32 lath electrode with argon flow at 20 cfh settings are dc with current ranging from 10 to 50 amps the butt joints are fit fairly tight but you can see light through the gap my problem is the edges of the steel melt away and open holes almost. Make sure to use an electrode wire that is thinner as it uses lesser heat and prevents blowing holes on to the sheet metal.
