Definition of weld screw: a screw that has a flat offset head and can be made captive by spot welding.

Although welding a bolt is not an ideal solution to many engineering issues, it may sometimes be necessary. … It should be noted that certain bolts’ grades and size can make it impossible or unsafe to weld them. Welding on a heat-treated bolt will weaken it because it would heat the bolt beyond its tempering point
