Can I weld A333Gr6 LTCS pipe to A106 Pipe ??
Can I weld A333Gr6 LTCS pipe to A106 Pipe ??
(OP)
Due to non availability of A106 pipe material, we need to weld an existing A106 pipe to an available A333 Gr6 LTCS pipe for a Reactor outlet piping modification.
Can I weld A106 Pipe to A333 Gr6 pipe?
If yes, Shoule be the use of E/ER7018 or E/ER8018 welding wires ok for this application? Any other precautions to be taken fr this welding?

i also feel so....the difference is impact tesing & minor chnages in chemical composition..

good point about difference between 106A and B grade. Correct me if I'm wrong but it is correct to use the low hydrogen E7018 as you recommended but just have to use an impact tested WPS as the concurrent requirement.

I always specify low hydrogen electrodes when it comes to welding code applications or otherwise. Regarding your statement about an impact qualified WPS, I can't really provide an answer to your question because you may not need an impact qualified WPS for this modification, the OP is using A 333 Grade 6 material as a substitute for originally installed A 106 Grade ?.
