Friction welding belongs to the category of pressure welding technology, which relies on the frictional heat generated by workpiece rotary movement to heat the welding ends until they reach a fully thermoplastic state. Once the ideal plastic temperature is achieved, rapid upsetting pressure is applied instantly to complete solid-state joining, delivering stable welding quality, high joint strength and outstanding production efficiency.

Principle of friction welding：
Friction welding is a pressure welding method that uses the heat generated by mutual friction in relative rotational motion when the workpiece contacts the end surface, so that the end reaches the thermoplastic state, and then quickly upsets to complete the welding. The most common friction welding method， When welding two circular cross-section workpieces, first make one workpiece rotate at a high speed about the centerline, and then apply axial pressure to the rotating workpiece to start friction heating. When the specified friction welding time or the specified amount of friction deformation is reached, that is, when the joint is heated to the welding temperature, the transfer of the workpiece is immediately stopped, and a greater axial pressure is applied to perform upsetting welding. Usually, the entire welding process only takes a few seconds.
Advantages of friction welding ：
*The welding quality is good and stable. The rejection rate is about 0.01%, and the rejection rate of flash butt welding is 10%-1.4%.
*High welding productivity.
*The production cost is low, and the power of the welding machine is small and the welding time is short, so it can save electric energy. Compared with flash welding, friction welding can save about 80-90% of electric energy. In addition, the welding margin of the workpiece is small; the workpiece does not need special processing and cleaning before welding; sometimes the welding flash does not need to be removed; there is no need for filling materials and shielding gas. Therefore, the processing cost can be reduced by about 30% compared with arc.
*The friction welding machine is easy to realize automation. Operation and maintenance are simple and easy to master. The work site is clean and there is no harmful gas from sparks and arcs.
