I'm fabricating caps for the walls on a powdercoating oven I am making. The walls are 48" by 47" but my sheetmetal brake is only 30" wide, therefore I have to fabricate the caps from 2 pieces. So when I weld the pieces together (20 gauge sheetmetal, TIG, 30amps), I get some deviation towards the open side.I tried clamping an iron angle inside the closed side but I still get some deviation. Is there any way I can avoid this so that the caps stay straight?Thanks in advance (I am relatively new to all this and slowly learning).
Reply:Low heat and multipass might help. JohnSMAW,GMAW,FCAW,GTAW,SAW,PAC/PAW/OFCand Shielding Gases. There all here. :
Reply:Yes, offset the parts before you weld. Seat of the pants will show you how much. David Real world weldin. When I grow up I want to be a tig weldor.
