[MW:19411] Re: Repair of Body cracks for A 217 Gr WC6

this type of weld repair procedure is called as stelliteing.

Essential requirements: 1. WPS for same or equivalent grade of material.

                                   2. A good welder qualified for welding especially insitu welding.

                                   3. PQR

For Vinod : i have experienced same issue for one of my repair project on an Marine Boiler Superheater Valve having same material composition of SA 217 WC6.

You can use ECoCr-A welding electrode for welding (SFA - 5.13)

PWHT depending upon thickness.

 

Cheers,

Sharafat Dhanse.
