Traditional platen motion control in flash welding is based upon the continuous advance of a predetermined rate of velocity. The instantaneous change of the contact bridges is not taken into consideration in this control method and so the method has obvious limitations in regard to the improvements in flashing performance and raising heating efficiency.This paper introduces the principle of an instantaneous control of the platen motion in flashing welding,i.e, instantaneous regulation of the platen motion in the course of making and breaking contact bridge during flashing. This control method can regulate the burn-off process of contact bridge according to requirements so that the required flashing voltage is lowered and the flashing heating efficiency raised.Moreover, by instantaneous control of the platen motion, the macro rate of velocity of the moving platen can be self adjusted to fit the change in burn-off rate of the flashing interfaces and a platen displa cement curve with similar shape as a ponential function can be automatically established.Application tests of this instantaneous control on a conventional flashing welding machine, show a stable flashing performance, yield high quality welds, and decrease the required specific power to one tenth.

传统的闪光焊动板控制是以给定速度持续送进为基础的,这种方法不考虑触点的瞬时变化,因而在改进闪光过程和提高加热效率方面有着明显的局限性。本文提出了一种闪光焊动板瞬时控制原理,即按照闪光时触点的产生与烧化过程对动板进行瞬时调节。这种控制方法可以根据要求改变触点的烧化过程,从而降低激发闪光所需的电压,提高闪光加热效率。对动板进行瞬时调节,还可以实现动板宏观速度自适应于工件烧化速度的变化,自动形成具有类似指数函数形式的动板位移曲线。本瞬时控制法在常规通用焊机上的应用试验表明:闪光过程稳定,焊接质量良好,可以降低比功率到十分之一。
