Skipping pre-heat on that pressure vessel weld was my biggest blunder
I was fixing a leak on an old boiler and thought I could weld it cold to save an hour. The bead laid down fine and passed a visual check. Come hydro test time, we heard a sharp ping and saw a crack running the full length. Had to drain everything, cut out the section, and re-prep the edges from scratch. That one choice wasted a full shift and put the whole job behind schedule. My crew lead gave me an earful about lazy habits costing real money. Now I won't touch a joint without a temp stick and a torch first. It's a hard lesson, but rushing always bites you in the end.

What kind of pressure was that vessel holding when it let go? I've seen guys skip steps on low pressure stuff and get away with it, but it sounds like this was a serious piece of equipment.

Rushing to save time usually ends up costing more in the long run. I see it all the time with people trying to skip steps on simple tasks, like packing a truck without proper padding. They think they're being efficient, but then stuff breaks and they have to redo everything. Your weld crack is a perfect example of that mindset hitting hard. Shortcuts just aren't worth the trouble.

Ever notice how shortcuts always seem to double the work? I did something similar once using regular bolts where I needed hardened ones, and the whole assembly let go under load. That rush to finish just guarantees you'll be starting over from scratch.
