Why 6010 root 7018 fill?
Why 6010 root 7018 fill?
(OP)
I do structural but I have become the "go to guy" for a contractor and he was asking me about boiler pipe welding. He told me, and I've found thorugh some internet searches, that the pipe welds usually use 6010 rod for a root pass and 7018 (or others) for subsequent fill and cover passes. Why is that? It turns out the welders used 6010 for all passes and they were asking me if it was OK. I couldn't seem to figure it out so I told the guy to talk to whomever or whatever authority was requiring it (mechanical engineers? ASME?), but now I'm curious and nobody around me seems to know.

ASME B&PV Code and most piping codes do not get into process details like the above.
