    • A method and an arrangement for friction welding foamed thermoplastic parts, wherein a first foamed plastic part (4a) on a first carrier body (2a) and a second foamed plastic part (4b) on a second carrier body (2b) are accommodated with respect to one another in such a way that a first contact face (22a) of the first foamed plastic part (4a) and a second contact face (22b) of the second foamed plastic part (4b), to be welded to the first contact face (22a), are pressed in a planar fashion one against the other by the first and second carrier bodies (2a, 2b), and the first and second carrier bodies (2a, 2b) are moved with a predefined frequency and amplitude relative to one another in parallel oscillation planes (14a, 16a; 14b, 16b) are distinguished by the fact that the first carrier body (2a) is moved at a frequency of more than 450 Hz, and the acceleration which the first carrier body (2a) experiences during its movement is greater than 4000 m/s2 at least during a partial section of the movement path, that the first and second contact faces (22a, 22b) are spatially shaped and run parallel to one another and the surface normals (24a, 24b) at each point of the first and second contact faces (22a, 22b) have at least one component which runs parallel to the surface normal (18a, 18b) of the first and second oscillation planes in which the first and second carrier bodies (2a, 2b) are moved relative to one another.
    • 一种方法,以及用于热塑性泡沫塑件摩擦焊接,其中,在第一支承体(2a)和一个第二泡沫塑料部分的第一塑料泡沫部分(4A)(4B)的(2b)中以这样的方式即第一接触面彼此相加到第二支承构件的布置 该第一泡沫塑料部分(4a)和第二部分(22a),与所述第一接触表面(22a)上待焊接的接触面(22b)的所述第二发泡塑料部分(4b)中由所述第一和第二支撑体(2A,2B)的表面彼此压靠和所述第一和 第二支承体(2A,2B)相对于彼此在振动的平行平面(14A,16A; 14B,16B)以预定频率和振幅被移动,其特征在于,所述第一支撑构件(2a)的具有频率大于450赫兹 被移动和加速度,这在其运动期间学习的第一支承体(2a)中,至少在EI 移动路径的网元部分截面是大于4000米/秒2,在第一和第二Kontktfläche(22A,22B)在空间上成形,并且平行于彼此和表面法线(24A,24B)(在第一和第二接触表面22a的每个点,22B ),其具有至少一个平行分量与表面法线(18A,18B)延伸的第一和第二振动面,其中(第一和第二支撑体2A,2B)相对于彼此移动。
