Hi all,
Sorry, I'll have to keep this quick.
I'm trying to learn how to TIG weld, and am currently trying fillet joints. I'm experimenting with currents in the region of 25-32A, on 0.8mm CR4 mild steel.
The front of the weld looks okay, but the rear face has a concave appearance, which I can't believe is correct.
Can anyone, please, let me know what's wrong. I've tried changing all sorts; gas pressure (6-10 l/min), current, arc length and tungsten size (1.0mm or 1.6mm). Even, as a last resort, filler material; 1.0mm or 1.6mm.
I just can't think of what else it could be. Oh, and yes, I have cleaned the material prior to welding.
I've attached three pictures - front face, rear face, and the underneath.
Obviously ignore the hole. It was part of the experimentation.
I can't find any details anywhere about the rear face of fillet welds. Apologies if I've missed something obvious!
Many thanks!
