Flaw Excavation and Weld Repair
|
-This method involves Grinding out the defects and apply protective coat. -Depending on the type and location of the flaw, and the type of base metal or weld material, excavation can be accomplished by mechanical removal methods or by thermal removal methods -The Repair process shall follow ASME PCC -2 |
