Friction Welding Machine for Precision Metal Joining

Friction Welding Machine for Precision Metal Joining​   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 is realized by a Rotary Friction Welding Machine; when welding two circular cross-section workpieces, the Rotary Friction Welding Machine first makes one workpiece rotate at a high speed about the centerline, and then applies 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 rotation 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 s…
