FRICTION WELDING ALUMINIUM

Friction stir welding is a newly developed technique which promises to alter radically the approach to welding aluminium plate and sections, and is likely to be of interest to the fast ferry industry. The method involves plunging a rotating probe into the seam to be welded and then moving the probe along the joint under high pressure. The material is heated by the resulting friction to the point where it softens and unites behind the moving tool to create a welded joint. Throughout the process the temperature remains below the melting point. The method is said to be ideal for straight profiles and flat plates up to 30mm thick.
