Welding is a great way to build a robot frame. Very strong and lightweight. You would be amazed at the pounds you can save by eliminating all the fasteners and joining hardware. However, an FRC robot frame should really be TIG welded by an experienced professional. Also, issues can arise such as heat affected zones, and warping. If done properly, welds should not break, however you should have a plan to fix it by bolting/etc if you do happen to break one at competition.
