The automatic brazing equipment based on penetration-brazing was developed for heating cables to process butt joint on Cu-Ni dissimilar metals. The total configuration and welding process on the automatic brazing equipment was introduced. The power system of special butt brazing was analyzed, its main circuit adopted single phase AC voltage controller. The PLC for coordinated multi-axis control was used in control system. The special butt brazing machine had been used and the microstructure and mechanical properties of butt joints were investigated by scanning electron microscope and tensile testing. The results showed that the automatic brazing equipment had good portability and could accomplish the butt welding on Cu-Ni well. The welding efficiency was enhanced and welding quality could be ensured.
