Ok, this popped into my head today and I can't wait until next week to ask my instructor. I've searched all my books and can't find an answer.
Say for example that you have a butt joint - 1/4" steel, prepared with a groove, 1/8" root face. Would you set your welder up as if you were welding 1/4" material or 1/8" material and run multiple passes? Maybe this isn't the best thickness to illustrate what I'm trying to say but hopefully you'll understand what I'm getting at.
I've gone over this so many times in my head I'm starting to confuse myself as I can see pros and cons to both.
p.s. Apologies to the two people who read my question before I came back and edited it for clarification.
