In recent years, following the attention of the automobile industry to reduce the weight of cars, the use of alternative materials with lower weight and better mechanical properties has been the focus of these companies. In particular, hot-stamped boron steel has been considered as an alternative material due to its good mechanical properties. This material is used to reduce the weight of the frame due to its reduced thickness, excellent performance and good performance. Considering that hot stamping of boron steel causes oxidation and carbon deposition on the surface, the use of surface coating is necessary to prevent these cases. This coating layer itself causes side problems such as the narrowing of the weldable range and also the reduction of mechanical properties during resistance welding. Therefore, in this study, we introduce research performed to improve the weldability of Al-Si coated hotstamped boron steel in terms of the material and process.
