This study aims to understand the thermal and mechanical behaviors of dissimilar stainless steel and carbon steel welds during welding.
Utilized a combined experimental and finite-element simulation approach.
Performed welding using flux-cored arc welding with specific parameters.
Modeled temperature fields during welding with a Goldak double-ellipsoid heat source.
Conducted microstructural analysis and tensile testing to assess failure mechanisms.
Predicted peak temperatures of 1350 °C at the fusion boundary.
Identified significant microstructural transformations, including martensite formation in the heat-affected zone.
Observed local hardness peaks of 620 HV in carbon steel HAZ, contrasting with lower values in weld stainless steel.
Confirmed that tensile failure occurred within the carbon steel HAZ, correlating with high residual stresses and brittle phases.
