摘要：
The invention relates to a method for producing a piston (1) of an internal combustion engine, designed as a one-piece cooling channel piston. The piston (1) comprises an upper part (2) and a lower part (3) supported by corresponding circumferential joining bosses (11, 12) together forming a joining zone (4). In order to produce a bonded joint of the upper part (2) and the lower part (3), the joining bosses (11, 12) are connected by means of multiorbital friction welding in the region of a rotationally symmetrical or rotationally asymmetrical joining zone (4).
