摩擦焊新工艺简介摩擦焊是一种金属固相热压焊,它利用两工件作相对高速旋转并轴向加压,使摩擦生热,促使两工件的接触表面达到焊接温度(接近于金属熔化温度),然后瞬间停止旋转,并再施加较大轴向顶镦压力,使两工件结合面金属实现原子的相互嵌入、扩散形成牢固的焊接接头。其动作特征示意见图1。摩擦焊可以焊接黑色金属、有色金属、同种或异种金属:甚至可焊非金属材料如塑料、陶瓷等。其可焊性很广泛,常用材料的可焊性见表1。焊接接头型式有对接或T形接头,两焊接工件可以是圆棒、管、板等。各种焊接工件应用实例见图2。摩擦焊机分连续驱动式 Friction welding new process Introduction Friction welding is a metal-solid-state thermocompression welding, which uses two relatively high-speed rotation of the workpiece and the axial compression, the friction heat, to promote the contact surface of the two pieces of the welding temperature (close to the metal melting Temperature), and then stop rotating moment, and then exert a greater axial top upsetting pressure, so that the two workpieces with the metal surface to achieve atomic mutual embedding, diffusion to form a solid welded joints. The action characteristics shown in Figure 1. Friction welding can be welding black metal, non-ferrous metals, the same or dissimilar metals: even non-metallic materials such as plastic welding, ceramics and so on. Its solderability is very wide, the weldability of commonly used materials in Table 1. Welded type of joint docking or T-shaped joints, two welding pieces can be round bars, tubes, plates and so on. A variety of welding workpiece application example shown in Figure 2. Friction welding machine points continuous drive
