Omfang

This standard applies to welding processes where the skill of the diver-welder has a significant influence on weldquality.This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements andcertification for the approval testing of diver-welder performance for the welding of steels underwater in hyperbaricwet environment. The recommended format for the certificate of approval testing is given in Annex A.During the approval test the diver-welder should be required to show adequate practical experience and jobknowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to beapproved, information on these aspects is given in Annex B.This standard is applicable when the diver-welder's testing is required by the purchaser, by inspection authorities orby other organisations.The welding processes referred to in this standard include those fusion welding processes which are designated asmanual or partly mechanised welding. It does not cover fully mechanised and fully automatic processes (see 5.2).All new approvals should be in accordance with this standard from the date of this issue.However, this standard does not invalidate previous diver-welder approvals made to former national standards orspecifications, providing the intent of the technical requirements is satisfied and the previous approvals are relevantto the application and production work on which they are employed.Also, where additional tests should be carried out to make the approval technically equivalent it is only necessaryto do the additional tests on a test piece which should be made in accordance with this standard.
