Specification and qualification of welding procedures for metallic materials. Welding procedure test - Laser-arc hybrid welding of steels, nickel and nickel alloys1 Scope This part of ISO 15614 specifies how a preliminary welding procedure specification is qualified by welding procedure tests. This part of ISO 15614 defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of variables listed in Clause 8. NOTE 1 It is possible that additional tests are required by applications standards. NOTE 2
