It is a welding method that use the frictional heat as a heat source generated by relative movement of metal materials while pressurizing them.
Unlike traditional welded joints, rotation and pressure is applied. So the complex high-temperature processing accompanied by phenomenal jointing.
Those who have experienced in drilling, you probably know that, when drilling holes by using a drilling machine, the edge of the drill becomes abrasion or polishing condition is poor. Also, edge of the drill is turning bright red. In the end, it becomes one with the work & have you ever had it wouldn’t come off?
We believe this is the root of friction welding.Also, friction welding allows for joint different materials that are impossible with traditional method. Furthermore, it is possible to reduce the cost by using expensive materials only for necessary parts.

Advantages of using friction welding
1.Material cost reduction
By friction welding of same materials and different diameters materials, it is possible to reduce the machining of round bar material costs & processing costs.By friction welding of different metals, it is possible to use expensive materials only where
necessary and the rest can be replaced with cheaper materials.
2.Reduce processing costs
If the product has a shape that is extremely difficult to process in one piece, processing can be made easier by dividing it into two parts and applying friction welding after processing one part.
