Heat treatment after welding: from skip to standard
I always saw post-weld heat as extra work for no gain. Then a boiler we built developed cracks in the seams too soon. The fix was costly and a real headache. A senior welder explained how heat relieves internal stress. I make it a point to include it now, and it works.

My old boss used to call me "Skip" because I'd always try to cut corners. I learned the hard way too, just like @elliotshah, when a big bracket I welded for a conveyor snapped clean off after six months. That extra hour for heat treatment feels like nothing compared to redoing the whole job from scratch.

Ever skip a step thinking it's just busywork? Learned a similar lesson with a trailer frame. Didn't stress relieve it, and the thing shook itself apart on a rough job site within a year. That sinking feeling when you see the crack is the worst. Now I just factor the extra time in, because fixing it later is always ten times the hassle.
