Dear All,
My site contractor to do pipe long seam welding of SA516 GR. 70 + SS316 cladded plate material. Back chip is not accessible of this joint.
They have query, if first complete SS316 welding by using 316 electrode/ filler wire & subsequent layer will be E- 309MO & E- 7018.
Is it acceptable? I think they should do welding with E- 309MO up to carbon steel after 316 welding.
Please advice.
Regards,
Sachin A Kavathekar
