Effect of Welding on the Physical and Mechanical Properties of Dissimilar Metals Weld Between S355J2+N and S690Q Steels

WeldingWelding is one of the most commonly used metal joining processes, along with the development of weldingWelding technology there is a weldingWelding process between different types of materials such as weldingWelding different types of material between S355J2+N and S690Q steelSteels. During the weldingWelding process, sometimes there is a discrepancy in the results so that the weldingWelding process needs to be repaired, in the weldingWelding repair process, the different types of material between S355J2+N steelSteels and S690Q steelSteels the phases that appear in the HAZ area are ferrite and cementite. In the HAZ area, weldingWelding that undergoes a phase repair process becomes coarser and has a smaller hardnessHardness value than in the weldingWelding process of different types of materials that do not undergo a repair process. This is possible due to the repeated heating process in the HAZ area.
