Can I weld my cam bolts?

I always try to set them by taking them in too far, and then rotating them out to where I want the camber to be. That way the cam washer is riding hard on the inner adjuster lip. If I hit a pot hole, it's going to try pushing the upper control arm inwards, not out. I'd try epoxy before I welded anything up in there, at least in the future if you needed to take it apart, you could put a little heat to it and melt the epoxy. Trying to get a grinder up in there would be a PITA.
