The parking brake cable has worn a fairly deep hole into the lower flange on my frame. It's worse on the driver's side at about 3/8" deep (pictured). I think I could just fill it with the welder and then grind it, but how does this affect the frame? Will the heat weaken anything? Would it change anything if I welded slower/faster? Yeah I'm over-thinking, but I want to do it right, and I wanna learn something too!
