Microstructure and Bending Strength of Dissimilar SS400/SUS304 Steels T-Fillet Joint by Gas Metal Arc Welding

Abstract:

In this paper, experiments on welding a dissimilar SS400/SUS304 steel T-fillet joint using high chromium electrode, and an effect of welding current on joint properties were studied. T-joints wielded by the designed specific welding currents were mechanically prepared and systematically investigated for joint properties. The experimental results were summarized as follows. Dissimilar SS400/SUS304 steels T-fillet joint could be successfully welded using a gas metal arc welding process with no defect in a weld metal. The optimized welding current in this experiment was 160 A that showed the least crack length of 0.247 mm. from a bending test. A different chemical composition of low carbon steel and high chromium weld metal produced a small interface shown with a smaller mixed zone of reinforced elements and base metal. It was also affected to decrease in the joint strength. However, the increase in the welding current could increase a combination of reinforced elements and a base metal on the interface, and it showed an effect to increase in the joint strength.
