I am only just getting ready to weld aluminum. I'm pretty experienced at steel, but what I'm wondering is if aluminum plate (GMAW welded with argon shielding gas) warps more, less or about the same as steel plate? A guy wants me to make him up a simple weldment from 1/4" 6061 plate but it has a bunch of 90° angles in it I'd have to weld, and I don't want them to be way off. For steel I normally just fit the angle up about 2° shy of where I want it and let the weld pull it square, then I correct it with a BFH or hydraulic press if needed.
