適用范圍：This standard specifies acceptance conditions for the approval of welding consumables for underwaterhyperbaric wet welding of non-alloy and fine grain steels with a minimum yield strength of up to 420 N/mm2. Itshall be applied when tested and approved consumables are requested by clients, certification authorities orother official bodies.The standard covers procedural requirements for testing consumables for welding processes 111 and 136which are carried out manually or semi-mechanically in wet hyperbaric conditions. To date, practicalexperience has only been made with these two welding processes, and this standard does not coverconsumables used for underwater welding in dry hyperbaric conditions.This standard covers only procedural requirements for testing welding consumables for use in wet hyperbaricconditions. 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 ofwelding consumables for hyperbaric welding in wet conditions indicated by symbols or abbreviations given inaddition 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 fromresults determined in production welding. Such discrepancies are the result of differences in the weldingprocedure (such as the diameters of electrodes or wires, process performance, welding position and materialcomposition).
