How many times PWHT one can perform on SA2335P91 Joints ? what issue may arise if we do PWHT multiple times on such joints . give scientific reasons.
what if the material is carbon steel or low alloy steel?
Please see the attached positive material identification results. One component is SS 316 and another is Copper. Kindly suggest which welding consumable ( electrode /filler ) shall be suitable for welding of these parts . What precautions to be taken while doing this welding.

Dear All,
which filler wire with AWS classification we can use for welding Chinese material 12Cr1MoV . We are currently using Chinese Filler wire R-31 for welding 12Cr1MoV, but this filler wire is currently not available in our stock in india.
Thanks
