Description

Technical Field

[0001] The utility model relates to the technical field of friction welding, in particular to a friction welding device for processing automobile parts. Background Art

[0002] Friction welding refers to a method of welding by using the heat generated by the friction of the workpiece contact surface as a heat source to cause the workpiece to produce plastic deformation under pressure. Under the action of pressure, the relative movement between the welding contact end faces generates friction heat and plastic deformation heat on the friction surface and its vicinity under constant or increasing pressure and torque, so that the temperature of the area near it rises to a temperature range close to but generally lower than the melting point, the deformation resistance of the material is reduced, the plasticity is improved, and the oxide film on the interface is broken. Under the action of the forging pressure, the material produces plastic deformation and flow, and the solid-state welding method is achieved through molecular diffusion and recrystallization at the interface.

Therefore, during the detection process, there will be a certain error due to manual control when approaching the center, which will cause low alignment accuracy and reduce the friction welding yield of the workpieces.
