I've got this hub that's been ground down on the end, for what reason I don't know. It'll work fine as is, but I want to add weld and grind to it's original shape. So, it's cast, it's got a thin parting line so it's not forged. I have 316T wire that I've used before for cast and it seems to work fine but never stress tested. My method is start the weld in one spot, get it hot, then work the weld. Thoughts?
