I am working as a mechanical Engineer in a 1300 MW thermal power plant. currently working on a project of replacing around a mile length of mostly high pressure instrument piping.
Since piping is 1/2" nominal i am opting for a SMAW socket weld joints. it seems ok for most, but can anyone recommend A335P22 compatible filler materials and welding procedures?
i am also looking at some mixed joints incorporating A53GrB-SS304, A106GrB-SS304, A335P22-SS304.
Can anyone please help me out?
Thanks
