Sure, the welding is the easy part.
Having the right size cutter to recut the extractor slot, and then undercut the grooves for the "wings" is the tough part.

I don't think there is any way it could be economical- unless for a really valuable pistol; but then, why would it have been shot.

Just replace the breech block and move on.

No need to look for reasons related to the ammo or other, the darn block was just worn out, old, crystalized, or had a manufacturing defect or steel problem from the beginning and "finally" gave up after 100 years of use. JMHO.
