Rotary friction welding machine is a solid phase pressure welding method to realize welding, can easily connect the same or dissimilar materials, including metal, part of the metal matrix composite materials, because of its high productivity, rotary friction welding machine is favored, so what are the advantages and disadvantages of rotary friction welding machine?
Advantages of rotary friction welding machine
(1) The rotary friction welding machine has stable welding quality, high dimensional precision of welds, and lower rejection rate of joints than resistance butt welding and flash butt welding.
(2) The rotary friction welding machine has high productivity, which is 5 ~ 6 times higher than flash butt welding.
(3) Rotary friction welding machine is suitable for welding dissimilar metals, such as carbon steel, low alloy steel and stainless steel, high-speed steel connection, copper - stainless steel, copper - aluminum, aluminum - steel, steel - zirconium connection.

(4) Rotary friction welding machine processing cost is low, save electricity, welding parts do not need special cleaning.
(5) Rotary friction welding machine is easy to realize mechanization and automation, simple operation, welding work site without sparks, arc light and harmful gas.
Disadvantages of rotary friction welding machine
1, rotary friction welding machine by workpiece rotation, welding non-circular section is difficult. Disk workpiece and thin wall pipe fittings, because not easy to clamp and difficult to weld.
2. The rotary friction welding machine is limited by the power of the spindle motor of the welding machine. At present, the maximum cross-section of the friction welding can be 20000mm2. Friction welding machine one-time investment cost is large, suitable for mass production.
