摘要
对塑料超声熔焊特性进行了研究，烙焊过程中高频电功率可分为三个阶段，t1振动摩擦发热，t2熔焊为一体，t3能量过剩．熔焊拉力强度F随着单位体积所消耗高频电能P增加而提高，达到饱和状态，F达到他和后，继续增加P烙焊件焊缝凸起．
The characteristics of ultrasonic plastic soldering were studied. During the soldering the high frequency electric power may be divided into three parts, t1-vibration causes friction and heating, t2- components were soldered together, and t3-the excess power was left over.The soldering strength F increaJses with the power p lost in unit volume. When saturation was reached, the soldering seam will protrude with the electric power was increased again. The study is useful for developing automatic soldering equipment and for improving the ultrasonic plastic soldering.
