Specification and qualification of welding procedures for metallic materials. Welding procedure test - Fusion welding of non-alloyed and low-alloyed cast irons Ingestion-build-251241 The Defence Infrastructure Organization (DIO)1 Scope This part of ISO 15614 specifies how a preliminary welding procedure specification (pWPS) for production 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 within the range of a defined list of variables.
