Was on a boiler repair last Thursday. The weld needed slow cooling to prevent cracks. Boss pushed to finish early for a deadline. I caved and used fans to cool it fast. Big mistake. The metal contracted unevenly. Now there's visible distortion along the joint. Have to cut it out and start over. Never again.
I've got a two-week stint in Seattle servicing ship boilers. My background is in factory systems, so I'm out of my depth. What are the big differences I should prepare for?
