| Abstract: | Taken FH40 low-temperature high-strength steel for polar ships with different thickness specifications as the research object, the procedure tests are conducted with three methods, namely, Shielded Metal Arc Welding (SMAW), CO2 Gas Shielded Flux-Cored Arc Welding (FCAW-CO2), and Submerged Arc Welding (SAW). The results show that the welding joints meet the requirements of relevant specifications, and the mechanical properties meet the design requirements. The welding procedure parameters determined by the tests can provide guidance for the construction of new polar ships. |
