Hi! Mark.
I would not be happy with a weld and changes to molecular structure round
the hole , much better to re-tap it oversize ,but then it depends on
available metal as indeed a helicoil would.
Cheers

There is another method - get a welder to fill in the original hole, drill
and tap. I think I would trust that more than a helicoil, especially on
something that's proven to be a critical component.
Cheers,
