- Cladding TIG / MIG
– TIG with hot wire weld deposit for higher bonding response to base material as per MPS and approved WPS/PQR – material: 316 / Duplex / Super Duplex / Incolloy 825, Inconel 625 …
– Groove sealing area cladding by total filling of the groove before machining
– Verification of Fe dilution at 3 mm below surface, acceptance criteria as per MPS (5 or 10% max Fe content)
– Bore cladding: as clad condition within imposed tolerances (full bore machining upon request)
– Sealing area and face cladding 100% machined before testing
– 100% inspection of clad area by Ultrasonic tests / X-Ray / Dye Penetrant Test
– Application of repair procedure as and when required
