I was welding some t-stakes today and as always I tested them. I'm not the best welder and would rather have a failure in my yard then on the line. This time my welds held but the rebar shattered beneath the weld. This is smaller rebar than I'm used to welding. My best guess is that dunking it in water made it brittle. Any one else ever have this happen?
rebar can be a lityle tricky. just grind a bit of the scale off wherr your welding and maybe preheat then weld. I never had any crack (yet) but I been welding 30 + years. good luck, keep welding and have fun
