[0002] Diffusion welding is a commonly used welding technology. It melts the metal surface under high temperature and pressure to form a strong connection at the joint. It applies pressure to the two welded parts to produce plastic deformation at the microscopic uneven surfaces to achieve close contact, and then forms a strong metallurgical connection through heat preservation and mutual diffusion between atoms. It has the advantages of high strength, corrosion resistance, and no need for additional filling materials, and has become one of the indispensable welding methods in industrial production.

The graphite anode and the graphite cathode are connected to a heating pulse power supply through an electrode hoop. A thick welding piece is placed above the graphite cathode, and high-temperature solder, a thin welding piece, and an anti-deformation pad are placed from bottom to top directly above the thick welding piece. Flexible conductive paper is provided on the left and right sides of the high-temperature solder, and a low-loss pad is provided above the flexible conductive paper. It has the advantages of reasonable design, convenient operation, simple structure, easy control of process parameters, safety and reliability, etc.

[0004] However, in the implementation of relevant technologies, it was found that the low-deformation graphite electrode medium-frequency resistance diffusion welding device designed above has the following problems: in the above technical scheme, tungsten alloy is selected for the anti-deformation pads and low-loss pads. The low-loss pads are used to protect the welded parts from wear, and the anti-deformation pads prevent the welded parts from undergoing large deformation under pressure. However, when it is used, manual feeding is required, and manual feeding requires support for the material, which is more dangerous when the material is heated and welded. In view of this, an open diffusion welding device with size adaptability is provided to overcome the above defects. Utility Model Content
