This document applies to production welding and repair welding.
This document is applicable to fusion welding of steels covered by groups 1, 2, 3 and 8 in accordance with ISO/TR 15608 in a hyperbaric wet environment.
This document covers the following welding processes, in accordance with ISO 4063, applicable in hyperbaric wet environment:
— 111 manual metal arc welding (metal arc welding with covered electrode);
— 114 self-shielded tubular-cored arc welding.
The principles of this document may be applied to other steel groups and fusion welding processes not listed.
Three weld quality levels, A, B, and Z, are given in order to permit application to a wide range of weldments. Each weld quality level defines a set of criteria for weldment properties that shall be established during qualification.
This document does not address the selection of the weld quality level to meet the requirements of a particular application.
