I picked up some steel scraps and welded them together somewhat randomly to practice different scenarios: a long bead along a plate edge, a square tube welded to an angle iron and to a base plate, some T-joints, and a puddle test in the last photo. I’m self-taught, so I don’t have anyone to check my work.

What I already notice: my beads are greyish and darkened in some areas, they’re too convex and their width isn’t consistent, and I end up with big blobs at the end of my welds. My tungsten also sticks to the metal quite often.

My questions:
– Do my settings look right for this thickness?
– Is the grey color from too much heat or not enough gas coverage?
– Do you have exercises to improve consistency?

Process: TIG, steel scraps 2–3 mm thick, around 90 A.
