LCA's and ball joints - 73 B body

I know the LCA's are wasted as far as the threads - other than that they are structurally sound - I have read that ball joints can be welded in. This is my question , I know it's done more often on GM's as they're all press in and can have loose fits. Not concerned about the future of the LCA - I know I'll need new LCA's if/when I replace ball joints again.
