Had a 3/8 inch weld crack on a boiler tube at the Phelps plant in Kentucky
We were doing a shutdown job and found a hairline crack on a superheater tube after hydro. The root cause was a bad prep job from the night shift, leaving a thin spot. We had to cut out a 6 inch section and put in a new piece, which set us back a full day. Anyone else run into a bad weld prep that caused a major rework?

Bad prep is the worst, man. We had a similar thing on a header weld where the bevel was too shallow. The root pass didn't fuse right and it failed a bend test. Now we always check the fit-up and gap with a gauge before the first arc is even struck. Saves a ton of headache later.

So they just eyeballed it and hoped for the best? Classic move.
