Abstract (en)
[origin: WO2012171523A2] The invention relates to a welding tool (10) for connecting at least two workpieces (28, 30) in a connection region (32) by means of friction stir welding. The welding tool (10) comprises a probe (12) arranged along an axis (A) of the welding tool (10), for applying friction heat to the workpieces (28, 30), and a shoulder surrounding the probe (12), for separating the connection region (32) from the surroundings (22). The shoulder (14) is mobile essentially parallel to the axis (A). The invention also relates to a welding method and to a workpiece (33) that has been produced using the welding tool (10) or the welding method.
