The process requires no third party materials such as fillers, welding wire or gasses and is achieved by simply rotating one component part with a stationary component part. The resulting heat plasticizes the material which is upset or extruded from the faying surfaces, rotation is stopped and an axial forge pressure is applied to complete the process. The three key parameters of rotation, forge force and displacement are monitored throughout the weld cycle, resulting in a repeatable, robust and accurate finished component. Every weld is logged for total traceability.
Linear friction welding
This method uses oscillation instead of rotation and involves the rubbing together of two pieces of material while applying a load to produce frictional heat. The heating phase is rapid and efficient, producing a uniform heat affected zone. It ensures a very fast process, usually completed in a few seconds, with little or no joint preparation required. The result is a defect-free, solid state bond which achieves a 100% cross-sectional weld. No consumables or post weld treatment is required. Click here to find out more about the process.
