This document specifies how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests.
u000bThis document is applicable to production welding and repair welding.
u000bThis document is applicable to fusion welding of steels covered by groups 1, 2, 3 and 8 in accordance with ISO 15608 in a hyperbaric wet environment.
u000bThis document is applicable to the following welding processes, in accordance with ISO4063:2023, applicable in hyperbaric wet environments:
u000b— 111 manual metal arc welding (metal arc welding with covered electrode);
u000b— 114 self-shielded tubular-cored arc welding.
u000bThe principles of this document can be applied to other steel groups and fusion welding processes not listed.
u000bThis document specifies three weld quality levels, A, B, and Z in order to permit application to a wide range of weldments. Each weld quality level defines a set of criteria for weldment properties that are established during qualification.
u000bThis document does not address the selection of the weld quality level to meet the requirements of a particular application.
