Dear All,
We are working on PQR & deatails are as folows :
Appl. Code - DNV OS F101,2000
PQR - Through THickness Repair. (SMAW)
Base Metal - API 5L X GRADE 60 - 12.75" OD X 14.3 mm THK.
Filler Metal - E-7018 H4R
Position -6G
After mechanical tests, we are getting all values in acceptable limits except All Weld Tensile results.(Reqd- 517 Mpa & Actual - 483 / 493 Mpa)
What is the reason & solution for the same?
Pl. reply.
