<p>Disclosed is a method for joining at least two parts (2, 4) by an overlap joint, wherein in the case that the parts (2, 4) have different melting points the part (2) having the lower melting point is positioned on the part (4) having the higher melting point, a tool (6) having a shank (8) and a broadened head (10) is positioned in a tool holder (26), wherein a contact surface (20) of the head (10) extends over the tool holder (26) in feeding direction, the tool holder (26) rotates and the tool (6) is pressed with the shank (8) against the upper part (2) in the direction of the lower part (4) until the shank (8) penetrates the upper part (2) and the lower part (4) and the movements of the tool holder (26) are stopped when the upper part (2) is clamped between the lower part (4) and the tool head (10), and an overlap joint.</p> |
