Do Not use right angles if possible. They only collect heat as you start and stop welding, and that can make warping.

I share your opinion about the right angles vs. curved cuts. I know how heat will run to a corner (least resistance), so I consider heat transfer to adjacent panels whenever I am welding. If I have to cut a 90, that is where my last welds will be.
