My concern would be if there's anything there to weld. I'm
no expert but you might want to talk to a plater about the
piece before you attempt a repair... You might have a
part that is chrome on iron oxide rather than chrome on
steel. To replate it, the old chrome has to be removed.
That process might determine whether you have any thing
left to weld...
