Diffusion Welding Equipment Composition and Structure

The main and secondary factors of vacuum diffusion welding and LF21 are heat preservation time, heating temperature and applied load in turn. The level is heat preservation time 60 min, heating temperature 540 C and applied load 4 MPa. At this time, the strength of welded joint is very high. The diffusion rate of copper is relatively faster than that of aluminium. The diffusion zone basically distributes on the interface of aluminium side. The hardness of the diffusion zone is much higher than that of the base metal. The intermetallic compound CuAl2 was formed at the interface between diffusion zone and copper matrix of the Cu/Al joint, and the eutectic of alpha(A1)+CuA12 was formed at the interface between diffusion zone and aluminum matrix. The metallurgical bonding of copper and aluminium was realized in the diffusion zone.

Polymer diffusion welding equipment is a kind of welding equipment, which joins copper and aluminium weldments tightly at a certain temperature and pressure for a period of time, and makes atoms between the contact surfaces diffuse to form a joint. The main factors affecting diffusion welding process and joint quality are temperature, pressure, diffusion time and surface smoothness.

Diffusion welding has the advantages of no solder, traceless welding, smooth workpiece appearance. The equipment can adjust the output current and pressure, so that the workpiece can get a reasonable heating speed. The workpiece clamping mechanism adopts oil pressure control system, which makes the clamping of the workpiece stable and stable.

The main function of the polymer diffusion welding machine is to realize the diffusion welding between materials and molecules. The equipment mainly produces electric power, chemical industry, smelting and other industries. It can produce bus expansion joints and soft-connected conductive belt products urgently needed by the industry. It can realize the diffusion welding between soft bus, soft bus and hard bus and hard bus. Diffusion welding.
