Well, I did a practice 3G welding certification test and it turned out okay. Basically, I welded up two plates into one. Ground the welds smooth. Cut two strips perpendicular and then bent them. One is an outside bend the other is an inside. There can be no cracks or breakage. I'll probably weld up a couple more before the inspector comes and I take the real certification test in a week or two. Then I'll be a state certified welder. Whoohoo!!
