Full Description
This document specifies how a preliminary welding procedure specification is qualified by weldingprocedure tests.This document applies to production welding, repair welding and build-up welding.This document defines the conditions for the execution of welding procedure tests and the range ofqualification for welding procedures for all practical welding operations within the qualification of thisdocument.The primary purpose of welding procedure qualification is to demonstrate that the joining processproposed for construction is capable of producing joints having the required mechanical properties forthe intended application.Two levels of welding procedure tests are given in order to permit application to a wide range of weldedfabrication. They are designated by levels 1 and 2. In level 2, the extent of testing is greater and theranges of qualification are more restrictive than in level 1.Procedure tests carried out to level 2 automatically qualify for level 1 requirements, but not vice-versa.When no level is specified in a contract or application standard, all the requirements of level 2 apply.This document applies to the arc and gas welding of steels in all product forms and the arc welding ofnickel and nickel alloys in all product forms.
