ISO specifies how a preliminary welding procedure specification is qualified by welding procedure tests. ISO applies to production welding, repair welding and build-up welding. ISO 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 qualification of this document. The primary purpose of welding procedure qualification is to demonstrate that the joining process proposed for construction is capable of producing joints having the required mechanical properties for the intended application.
