This part of ISO 15614 specifies how a preliminary welding procedure specification (pWPS) for production andrepair welding of non-alloyed and Iow-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 ofqualification for welding procedures for all practical welding operations within the range of a defined list ofvariables.This part of ISO 15614 is applicable to all new welding procedures. However, it does not invalidate previouswelding procedure tests made to former national standards or specifications. Where additional tests have tobe carried out to make the qualification technically equivalent, it is only necessary to do the additional tests ona 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 Iow-alloyed grey cast iron castings accordingto: 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 unalloyedand Iow-alloyed cast iron materials.
