Abstract (en)

[origin: CA3119929A1] The invention relates to a device and method for increasing the speed and increasing the stability of the welding pin in friction stir welding with the following device features: a) a tool drive (1) has a retaining flange (2) for a cone-shaped tool cover (3) with a union nut (4); b) an annular retaining ring (12) surrounds a pin shank (6) with a tool shoe (7) secured to the diameter of the retaining ring (12), wherein the tool shoe (7) has a smoothing and compressing surface (11) in the region of the pin tip (10) for smoothing the weld seam, wherein the pin shank has the width of the tool shoe (7); c) the pin tip (10) has an annular friction surface (9) which surrounds a screw conveyor (8) for the output of material transport from the pin tip (10), which has a thread running in the opposite direction to the thread of the pin tip (10).
