EN Magnetic-pulse welding is an innovative joining method that allows combining dissimilar metals. The article discusses weldability of copper rings with steel rods in order to study the possibility of using single-turn inductor. All specimens were welded with a discharge energy of 18 kJ. Significant deformations of copper rings were observed. Metallographic examination of welds revealed no defects. High-quality joining of metals in the welding zone with a characteristic wavy boundary interface was noted. However, to obtain more information on the exact mechanisms of weld formation, it is recommended to carry out numerical modeling of the process.
