Hi
I am a beginner that's been thrown in at the deep end somewhat..I have to weld in a patch to a box section on my car which is upside down. I'm lap welding 2mm to 2mm.
I've done a fair bit of practising off the car and thought I had everything dialled in nicely -
when I practice off the car I can make a nice T weld and good penetration on a vertical section. (I haven't been able to practice upside down yet though.)
However, as soon as I get under the car I struggle to get any penetration and just seem to create balls of steel that rain down on me. I have managed to get the patch stuck on but am not confident of its strength at all. It's the mounting point for the front subframe so it needs to be strong!
Anyway - I know earth clamps are one area to suspect , and plan on adding some braided earth cable to my clamp to improve the contact area. What I've seen people talking about upside down welding seems to relate to stopping the puddle from dripping - if I don't even have a puddle, is the earth a likely candidate?
any other ideas?
I'm using 0.6mm with 85% argon, sealey supermig 150.
