welding on threaded aluminum
I have a cast aluminum piece that is part of a convertible top mechanism. On one of the ends there's a threaded hole and the piece has cracked across the threads.
In lieu of being able to find a replacement part, welding the thing back together is the next step.
My question is how I should handle the threads.
Should I avoid them all together and weld around it best I can, or should I just go at it and go back and drill and tap the threads again?
A thought I had was to put a steel bolt or some other material in the threads and then weld. Kind of similar to how steel wire won't stick to copper or aluminum when plugging holes. I have a feeling that won't work though.
