Spent 3 years grinding welds wrong before a foreman showed me the trick
I was on a job in Baton Rouge last summer, working on a feedwater heater. Been doing this 8 years, thought I had my welding down pretty good. But this old foreman, Bob, kept looking at my beads and shaking his head. Finally he walked over and said I was grinding perpendicular to the weld instead of following the same direction. I had been making micro-cracks this whole time and never knew it. Soon as I switched to grinding parallel, my passes started passing x-ray every time. Felt like an idiot for not figuring that out sooner. Anybody else have a basic thing they did wrong for years without realizing it?
