As a Machinist in a roll shop we tried spray welding the worn bearing fits.(Undercut,spray weld, then grind to finish size) After the next 30 day inspection we discovered that it was chipping and breaking away. We went back to pre-heating, stick welding with Ni-Rod, and very SLOW cooling. Bearing in mind that this is just my experience with it and maybe others have better stories to tell. One more thing, no more than 0.030" thick if you try it. Good Luck! Rusty
