Abstract
The experience of application of qualification of surfacing procedure in accordance with the European standards is described. Main terminology, used in standards, is given and explained. Qualification of welding (surfacing) works at the enterprise is carried out by the outside independent expert body with an accredited test laboratory of non-destructive and destructive testing. During qualification the testing of procedures of surfacing on standard test specimens in the form of plates or pipes is carried out preliminary. As an exception the qualification of surfacing procedures is allowed on non-standard test specimens simulating the part being surfaced. The quality of deposited test specimens is checked firstly by using the non-destructive methods of testing. At the positive results of these methods of testing the specimens are subjected to the destructive methods of testing. If after testing the inadmissible defects were not revealed, then the expert body makes a protocol about qualification of surfacing procedure WPQR. 5 Ref., 2 Tables, 8 Figures.
