I have mentioned to my engineer other methods of welding such as fcaw but he seems to be content with short circuit. I was planning on building a bend tester tool and die to use in our press brake machine to test the welds also. I had some free time the other day so I beveled 2 3/8" plates and gapped them and did multiple passes in vertical down. After I got 2 test peices, I then took them to the press brake and bent them to over 90 degrees with 1" open and 10 ga. tooling thinking it would give me the most bend. I know this isn't a great idea, but I wanted to see my weld quality. When I bent the face side it failed because the weld pulled itself apart in the middle on the backside, not pulling apart from the steel on either edge though. The root side passed. Then, I took a test piece of unwelded plate, same size, and bent it just as much and the steel started to fail. So this gave me some confidence. What would I need to do for section 4 qual.?
