Qualification of welding procedures according to PN-EN ISO, ASME, DNV, AD 2000 MERKBLAT
In order to carry out qualification of welding procedures, it is necessary to produce weld specimens in advance, on the basis of which a preliminary Welding Procedure Specification (pWPS) is created. This is followed by the actual welding of the test joint and its validation through non-destructive and destructive testing, ending with the drafting of a Welding Procedure Qualification Report (WPQR). This is used as a basis for a Welding Procedure Specification (WPS), which is the main document for proper welding work. A correct specification defines the welding tools, type of weld, welded specimen edge preparation, basic welding parameters, type of substrate and filler.
Welding procedure qualification takes place in accordance with the following standards:
