- Scope
- This standard specifies acceptance conditions for the approval of welding consumables for underwater hyperbaric wet welding of non-alloy and fine grain steels with a minimum yield strength of up to 420 N/mm2. It shall be applied when tested and approved consumables are requested by clients, certification authorities or other official bodies. The standard covers procedural requirements for testing consumables for welding processes 111 and 136 which are carried out manually or semi-mechanically in wet hyperbaric conditions. To date, practical experience has only been made with these two welding processes, and this standard does not cover consumables used for underwater welding in dry hyperbaric conditions. This standard covers only procedural requirements for testing welding consumables for use in wet hyperbaric conditions. Classification of welding consumables is based on DIN EN 499 and DIN EN 758, and resistance, chemical composition and type of current used for testing are identified accordingly, with the suitability of welding consumables for hyperbaric welding in wet conditions indicated by symbols or abbreviations given in addition to the standard designation. In general, this suitability shall be tested using fillet welds. It should be noted that the mechanical properties of the pure weld metal established in testing may differ from results determined in production welding. Such discrepancies are the result of differences in the welding procedure (such as the diameters of electrodes or wires, process performance, welding position and material composition).
