<p>An improved method of friction stir welding is based on enhanced flow of plasticised material both perpendicularly and vertically to the longitudinal extension of the adjacent assembled members by exposing the created plasticised material to a perpendicular pressure along the surface of the members and causing simultaneous material flow along the probe pin in the vertical direction allowing the plasticised material to solidify behind the probe. A non-consumable probe (1) is provided comprising a concave bottom part (23) with an interchangeable pin (24) having surface of threaded configuration and in a preferred embodiment comprising two or more laterally protruding blades.</p> |
