Abstract:

This report describes the program of explosion bulge testing of 50 mm thick Australian sourced HY-80 steel plate, supplied by Bunge Industrial Steels PL to Industry Development Branch NSW Region to specification MIL-S-16216H SHIPS. The testing was undertaken as part of the qualification of this steel in compliance with U.S. NAVSEA requirements. The report deals with the first series of tests which were unsuccessful, the testing of unwelded plate, the development of manual metal arc welding procedures and the investigation of candidate welding consumables which ultimately led to a successful test series. The successful welds used low hydrogen electrodes of teh AWS 10018 M type supplied by Philips UK. The procedure followed a stringer-bead technique with strict limits on heat input, and a weld design incorporating a novel top-hat profile aimed at locating the weld toes potential crack initiation sites, well away from the remaining weld fusion boundary potential path for through-thickness crack propagation.
