new guy from vegas
Hey whats up guys! My name is Dan im 31 and currently live in las vegas nv. Ive always loved building things, i really got into the fabrication/custom auto scene when i got my first vehicle a 2000 blazer s10, i set out to make it something awesome, unfortunately halfway into the project other things sidelined me and it was untouched for years. Fortunately i got back into it last year and am pretty much done with the chassis and engine work which was extensive lol!. Now i want to learn metal shaping to do a one off body on the truck. I spent a long time focusing on and learning welding, fabrication,engineering, body work, polishing/finishing and never got to learning/doing what i really wanted, car body design/metal forming/mold work.
I put alot of time into learning tig welding as it is perhaps the most core skill, thats so easy to mess up (ever fabbed something beatiful just to ruin it minutes), in making custom cars. So ya just found this place and excited to finally learn this skill

Hello Dan and welcome to the site.
O/A welding might be your next process to learn. Jere

Is o/a the preferred type of welding for thin panels? Ive been tigging thin sheet by creating a perfect fit up and then autogenous welding the two together very fast with a very tiny bead while someone is purging the other side of the panel with argon. The weld gets full penetration and ive had pretty good results with no warping but i have little experience on larger runs like doors hoods etc. Does oa eliminate warping altogether?
I have done some oa welding its kinda like tig mechanically but the puddle acts much differently BTW i referring to how i weld on steel panels ive never attempted any thin panel work with aluminum, ive done tons of 14ga and thicker AL, lots of radiator/intake type work. Warping has never really been a problem at these thickness then again butt joints are rare for these types of parts

O/A welding leaves the weld seam softer than TIG because of the chilling effect of the argon flow. The seam will shrink using ether method but the O/A seam will be easier to planish out because the seam was allowed to cool at a slower rate. When planishing out cold you can control how much you stretch the weld and thereby maintain the shape of the panel.
