That gas pipe repair last week had me questioning everything I thought I knew about preheat
I was out at the Marathon refinery near Gary on Tuesday fixing a cracked steam line on a boiler. Foreman told me to skip the preheat chart because we were in a rush, so I just eyeballed it with a torch for 5 minutes. Three hours later the weld HAZ cracked right down the middle and we lost half a shift grinding it out and redoing it. Has anyone else had a foreman try to rush them on preheat and then act surprised when it fails?

That preheat chart skipping line hits home cause I read a weld failure report that said 80% of cracks come from rushing that step.
