I'm not sure if this is the exact term (tin can effect) but I read it in a classic car mag once.
I've weld successfully a new outer wheel arch onto a rear wing. The wing is thin and I had no problem with burn through. I'm a fairly experienced welder but this is the first time I've experience this problem. I cut out rusty wheel arches on an MR2 and butt welded the repair arch onto the wing. I'm getting distortion, which is to be expected, but it's the type where you can push the metal and it flexes inwards and outwards - ie. you can out your hand behind the panel and push it outwards or push it from the outside and push it inwards. Is this making sense?
Does anyone know how to fix this? thanks. Otherwise I'm happy with the weld.
