heat treating welded structures
(OP)
At our shop we have 2 differential housings from large equipment, it is a typical rear end with lots of gusseting welded to it. My question is i would like to releive it some from all the welding. I do not have access to an oven to do it properly. One of the guys on the floor recomended using a tiger torch then cover it with welding blankets over night. My worry is that now the housing is straight. Will applying heat unevenly (torch vs oven) cause warpage, and will it even do enough to help any? What temperature should i shoot for?
thanks
thanks

Can you take a scrap housing and experiment with it? If you're getting service failure because of fatigue cracks, SR can be a help. Also consider shot peening.
