Abstract
In this study, AISI 304 stainless steel and DUROSTAT 500 steel are combined using TIG double-sided arc welding. Microstructural differences of welded joints were researched by using a scanning electron microscope (SEM), an optical microscope, and electron backscattered diffraction. Mechanical properties of welded joints were investigated by microhardness, notch impact, and tensile tests. In addition, fracture surface morphology was evaluated using a SEM. The current power had a major impress on bead and hourglass shape. Maximum tensile resistance (677 MPa) was achieved at a welding time of 0.21 (m·min−1) at 460 (A) current, and the impact energy (116 J) was obtained. The weld metal consisted 41 wt% cementite, 25 wt% chromium carbide, 20 wt% martensite, and 14 wt% tetrataenite phases. With the increase in the current voltage, both bead and penetration sizes increased.
