    • The invention relates to a method for producing a friction-welded metal part having a shaft and at least one outer part, which is fastened to the shaft and has a greater diameter than the shaft and properties different from the shaft, comprising the steps of providing a blank for the outer part (1) having a round opening (5); providing a rod-like shaft blank (2) having an end section (6) that has a diameter greater than the inner diameter of the round opening (5) and that is centered with respect to the round opening; friction welding the end section (6) of the rod-like shaft blank (2) to the outer-part blank (1) in order to form a weld bead (4) by pushing the end section (6)into the opening (5), wherein the opening is expanded by means of the friction welding, until the end section hits the end of the round opening (5) and a welded-on outer part is formed on the outer part (1), wherein the weld extends conically in the outer part and the outer part surrounds the shaft blank; and shaping the blank thus produced in order to produce an outer-part contour by means of a method selected from among the following group: forging, upsetting, electric upsetting, extruding - all of the methods mentioned in the cold, warm, or hot temperature range. The invention further relates to a part produced according to said method.
    • 本发明涉及一种用于具有圆形开口(5)一种制造摩擦焊接金属部具有轴和至少比比轴柄和其它性质较大直径的附接的外部部分,具有一个空白的呈现用于外部(1); 与端部呈现的棒状轴坯料(2)(6),其直径对应于比所述圆形开口的内径的情况下(5)中,向被置于中心; 摩擦焊接的端部(6)的杆状柄的坯件(2)与外部坯料(1)至(4)根据所述端部的渗透形成焊缝(6)在所述开口(5)和延伸部分由摩擦焊接到端部的着陆 在圆形开口的端部(5),以形成在所述外部分(1),其中,在所述外部件的焊缝是锥形的并围绕所述轴坯料焊接外部部分; 这样产生由从以下组成的组中选择的方法来产生的外轮廓部的晶棒的形成:锻造,镦粗,电动镦粗,挤压 - 在冷或半热或温的温度范围内提到的所有方法。 此后做出一部分。
