[MW:2590] Re: welding rod selection for dissimilar materials

Dear Srinivas,

I think I forgot to mention, if the service condition is above 350 deg C, then have to use Ni -based consumable, like ENiCrMo-3 ..

below 350Deg C, you can use the consumables what I have mentioned earlier.

 

Regards,

Dear Srinivas,

If A335 Gr.P22 require PWHT depending on the thickness or service condition, then go for a buffer layer on P22 material with E309MoL , then perform the PWHT, after PWHT do the butt joint with SS316 using E316L consumable.

 

If, P22 doesn't require any PWHT depending on the thickness or service condition, then you can weld  with SS316 using E309MoL consumable.
