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.
