Qualification testing of welders for underwater welding - Part 1: Hyperbaric wet welding (ISO 15618-1:2016); German version EN ISO 15618-1:2016
Prüfung von Schweißern für Unterwasserschweißen - Teil 1: Nassschweißen unter Überdruck (ISO 15618-1:2016); Deutsche Fassung EN ISO 15618-1:2016
Overview
This International Standard covers the principles to be observed in the qualification testing of welder-diver performance for the fusion welding of steels in a hyperbaric wet environment. The ability of the welder-diver to follow verbal or written instructions and testing of his skill are therefore important factors in ensuring the quality of the welded product. Testing of skill to this document depends on welding methods in which uniform rules and test conditions are complied with, and standard test pieces are used. The general principle of this document is that a qualification test qualifies a welder-diver not only for the conditions used in the test, but also for all other conditions which are considered easier to weld in accordance with this document. It is presumed that the welder-diver has received training and/or has industrial practice within the range of qualification. This document is intended to provide the basis for the mutual recognition by examining bodies for qualification relating to the welder-diver's competence in the various fields of application. Tests are to be carried out in accordance with this document unless additional tests are specified by the relevant application standard when these should be applied. The welder-diver's skill and job knowledge continue to be approved only if the welder-diver is working with reasonable continuity on welding work within the extent of qualification.
