Hey guys, thanks for all the input. Let me explain my problem with a little more detail...
These box beams are typically 2ft wide, 4ft high, and about 100ft long. The web plates have a camber cut into them (about 1/8" per 10') for obvious strength reasons. We build them upside down on a jig...
We are building box beam overhead cranes and during the fab process weare getting a slight axial camber in the beam. The shop has been using heat to try and pull them straight, but with only limited success. Is there any information out there for a repeatable process for this?
