RFW-320
Custom Hydraulic Rotary Friction Welding Machine with Special Workpiece Fixtures
Main Advantages and Features
Compared with traditional fusion welding, friction welding has the advantages of high quality of welded joints, high welding efficiency, stable quality, and welding of dissimilar materials.
1. High welding precision and excellent joint quality. The welded joint can achieve strength equivalent to the base material.
2. Simple welding process with easy integration into automated and mechanized production. Suitable for welding a wide range of metal and non-metal materials.
3. The machine adopts a hydraulic semi-automatic continuous drive system, offering stable performance, high production efficiency, and low power consumption.
4. The Hydraulic Rotary Friction Welding Machine provides a clean and safe working environment with no sparks, arc light, or harmful gases, making it environmentally friendly and suitable for integration into automated production lines.
5. An optional flash trimming and slag removal device automatically removes welding flash after welding, improving operating efficiency and providing a cleaner, more attractive weld appearance. See Figure 1 for the finished result after flash removal.
6. Supports customized non-standard configurations and fixtures to meet the welding requirements of various special-shaped workpieces.
Main Applications
Horizontal Rotary Friction Welding has become a widely adopted joining technology in modern manufacturing due to its advantages of high weld quality, high efficiency, energy saving, and pollution-free operation. With the continuous development of advanced friction welding technologies, it has been increasingly applied in high-tech industries such as aerospace, aviation, nuclear energy, and marine engineering, as well as in power equipment, machinery manufacturing, oil drilling, and automotive manufacturing.
