Ask him for a code section requiring the weld. 250.104 certainly doesn't require it...it doesn't even require an irrecersable crimp, much less an irreversable connection.

It's not part of the engineer's requirements, is it?

I have seen it done during new construction when there was no gas present in the pipe. But if the pipe has gas in it, BOOM!
