Friction welding is a welding method "solid", by axial pressure and rotation of mechanical friction, so that the heat generating surface of the friction material in a semi-molten state, and then applying pressure piece, integrally welded firmly same or dissimilar metals.
The welding surface is melted together at both ends of the metal, and the connecting point is strong and tough, and the strength of tensile and torsional resistance far exceeds the strength of arc welding and argon welding.
1.Dissimilar materials can be welded together, For example, the stainless steel material can be welded with ordinary iron materials with various medium and high carbon steel materials, However,Require annealing after completed welding high carbon steel.
2.After welding, the materials at both ends are not easily deformed, Center eccentricity difference within 0.5m/m,To ensure the quality of the work piece can reduce the processing reservation,Can reduce materials and processing costs
3.The cost of production using friction welding is lower than that of forging, also It can be formed quickly. However, the strength is not less than of forged products, and the surface is cleaner.
4.It does not require the use of expendable materials such as fuels or metal-filled solvents, gases, etc., and generates uniform heat with friction between the contact surfaces, so there is no arc or toxic material to improve the working environment.
1.Optical scale positioning module

Advantages of servo control
Stable operation without being subjected to oil temperature. High-precision weld is possible. Angle control expands the range of the application of friction welding such as to phase adjusting workpiece. Servo control reduces more carbon dioxide emissions than hydraulic control dose. Better energy-saver. No oil leakage >>> Improved working environment. No waste oil >>> Environment-friendly. Feedback control of forge force enables smooth drive at low speed range. Uniform output under any conditions (temperature, humidity and so on) Downsized hydraulic unit >>> Space-saving and low noise.
