    摘要: A method for producing a rotationally symmetrical hollow metal part, particularly a shaft. According to the method, bar-shaped ductile solid matrial is provided, the solid material is heated from about 300° C. below the forging temperature to the forging temperature, the solid material is transversally spline-rolled until weakenings are created in the core zone (3) of the solid material and the sold material is torn open. Two mandrels (5,6) are forcibly introduced into the center of the bar-shaped solid material during the rolling process, and then one mandrel is retracted while the other mandrel continues advancing so as to produce a tubular part. A transversally spline-rolled rotationally symmetrical hollow part, especially a shaft, which is produced accoridng to noted method can be embodied as a transmission shaft, camshaft, drive shaft, output shaft, starter shaft, hollow shaft, or can bea preform for molded parts and the like.

    摘要: A method of friction welding a head part to a skirt part of a piston having a hollow cooling duct in which the internal connection surface of the first part to be welded is reciprocally arranged with an internal connection surface of the second part to be friction welded, so that they form a unsymmetrical contact area, so that the resulting weld of the first and the second parts produces a weld bead that is located predominantly outside of the hollow cooling duct. The unsymmetrical contact area can be formed by chamfered, angled edge surfaces that produce, for example, a wedge-shaped space, or partially matched, inter-fitting surfaces that remain out of contact and produce a gap at sides facing the hollow space.
