Reasonably ok with my mig welding on steel including repairs to rusty bodywork but I made my first attempt at aluminium bodywork and it was a dismal failure
From searches I may have been a bit optimistic but I have been asked if I can fill a hole cut for an exhaust in a land rover tub so this was vertical as well
This is about 1.3mm thick and I am using .8mm 5356 wire with argon and I couldn't even tack it despite having a sheet of steel clamped to the back of this to try and prevent blowthrough
I sanded back to clean metal and then used a new stainless brush in one direction only prior to welding.
I don't have ac tig and have no experience of tig anyway
I had one tack that was decent at 11pm everything else was pants
My other thoughts are to joggle a large sheet to fit in the hole and enlarge the drilled holes and plug weld it in place and then fill
or even to rivet (it is a land rover) a joggled sheet in and then fill
anyone have any suggestions that may speed me towards success
