[Steam-engine] welded boiler repairs

[Andrew]

I don't think it matters as long as you use an original part from the old
boiler, but if the new boiler is all welded the inspector is likely to
tell you to weld the steam dome on rather than rivet it back on, actually
they would most likely require that it be welded on at least in an
industrial setting, but I think it might be possible that they may allow
one to be riveted back on in the case of a portable or traction engine
boiler. I think that may be up to them.

To do the R stamp approved repair and use the dome but replace the boiler has already been established as acceptable.  What I was curious about is the use of welding.  Is it acceptable to reuse the dome, but change the method of attachment from riveted to welded?  It would seem to me that to consider that a repair the method would be the same.  That also applies to the boiler itself, is that considered acceptable as well?  It had welded stay bolts, where the original where threaded I'm sure. I am not an expert on the stamps etc, but was wondering  about the protocol.
