摘　　要：文摘从焊接材料、工艺参数、焊接面连接形式等方面综述了塑料超声波焊接对焊接质量的影响规律。低熔点、高表面摩擦系数的材料容易进行焊接,焊接质量主要受焊接时间、压力等因素的影响,导能筋及连接层的引入有利于提高焊接质量,并指出了塑料超声波焊接的发展方向。The paper introduces technique of ultrasonic plastic welding. Factors of welding quality include materials of welding, parameters of processing, interfacial shape of welding and so on. The materials that have low melting point and high external frictional coefficient are easy to weld. Primary parameters affecting welding quality are welding time,welding pressure, amplitude etc. Energy director or tie-layer materials are used to improve welding quality. In addition, the future development of ultrasonic welding technique in plastic field is pointed out.
