WPS for Inconel 600 and Incoloy 800H

Hi gent,

  1. I have drawing from the vendor, which mentioned end of the pipe was cladding Inconel 600.This pipe will be welded to SA 106 Gr.B
    How can I know which welding consumable is suitable for this requirement?

  2. Also, other drawing mentioned: the base metal is Alloy 800H. How I can choose the welding consumable?
    Thank you,

Corrosion Restant Overlay Procedure (CRO), that is specical process should carefully check in project requirement.

In my opinion, CRO procedure on carbon steel and HSLA overlay by GMAW / SAW with alloy 615 (AWS A5.14 ERCrNiMo-3).

  1. CRO on carbon steel without PWHT.
  2. CRO on HSLA (AISI 4130) with PWHT.

Additional buffer layer should consider in the new PQR (if required by Client).

The second question, I never did procedure and no advice.

Hope that help you!

Thanks for your information, all cladding from nozzle of equipment which follow ASME VIII div 2, for sure we will proceed new PQR. I intend to use SMAW AWS 5.11 ENiCrFe-3 to overlay on the normal carbon steel with same requirement of equipment.
