DIN EN ISO 15614-3:2008-06 Introduction Details of International Standards dealing with specification and qualification of welding procedures are g
25、iven in ISO 15607:2003, Annex A. Welding procedure tests for flash welding are presented in ISO 15614-13 and for friction welding in ISO 15620. 4 EN ISO 15614-3:2008 (E) DIN EN ISO 15614-3:2008-06 1 Scope This part of ISO 15614 specifies how a preliminary welding procedure specification (pWPS) for p
26、roduction and repair welding of non-alloyed and low-alloyed cast irons is qualified by fusion welding procedure tests. This part of ISO 15614 defines the conditions for execution of the welding procedure tests and the range of qualification for welding procedures for all practical welding operations
27、 within the range of a defined list of variables. This part of ISO 15614 is applicable to all new welding procedures. However, it does not invalidate previous welding procedure tests made to former national standards or specifications. Where additional tests have to be carried out to make the qualif
28、ication technically equivalent, it is only necessary to do the additional tests on a test piece made in accordance with this part of ISO 15614. Additional tests may be required by application standards. This part of ISO 15614 is applicable to welding non-alloyed and low-alloyed grey cast iron castin
29、gs according to: EN 1561; EN 1562; EN 1563; and EN 1564. The principles of this part of ISO 15614 are also applicable for welding cast iron to steel or to other unalloyed and low-alloyed cast iron materials. 2 Normative references The following referenced documents are indispensable for the applicat
