Effect of weld microstructure on the tensile properties and impact toughness of the naval, marine-grade steel weld joints

Effect of weld microstructure on the tensile properties and impact toughness of the naval, marine-grade steel weld joints

Pulsed direct current (PDC) gas tungsten arc welding (GTAW) of 12 mm thick plates of naval, marine-grade high strength low alloy steel (HSLA) using ER80S–Ni3 filler metal was investigated. The microstructural characteristics were examined by both optical microscopy and field-emission scanning electr...
