Key Word: Glitter of preface of Flash Butt Welding Process Parameters Monitoring Systemflashf is a kind of resistance welding craft to solder, because its have high speed intensity of efficient, welding line good, performance is good wait for a lot of advantage, in be being applied extensively at a lot of engineering fields such as car, autocycle, aerospace at present [1, 2] . The process parameter that affects glitter to receive head quality to solder is more, the interaction between each parameter, same parameter combines medium action to differ in different parameter [3] , solder of parameter timely collect and processing does not have significant step, this gives solder of quality blemish decide bring a lot of difficulty, especially the contact craze incident of a few small probability, make accurate it is more difficult to limit blemish to produce an account. Current, homebred glitter does not have corresponding parameter testing system mostly to welder, the systematic price that foreign equipment provides is high, the function is finite, accordingly, development develops can the trends that emersion quantifies solders process parameter testing system, problem of actual to solving production and rise solder equipment technology level has important sense. 1. The influence glitter main factor glitter to solder quality has glitter and upset to the main process of solder two phase, basically solder parameter has force of speed of allowance of overhang, flashy allowance, flashy speed, flashy current density, upset, upset, upset, clamping force to wait. Clamping force does not participate in glitter and upset directly, but need not measure; Through moving clamping apparatus displacement, gate (flashy) pressure of voltage, upset will reach secondhand the change of other parameter. In receiving production, actual solder often produces welder billabong, flash the right insulation side to welder is built as a result of the eyewinker namely receive not complete segregation, cause solder voltaic loss, because this detects,solder (network) electric current also is necessary. Graph 1 solder actually for what testing system place measures process parameter curve. Graph 1 solder Fig of process parameter curve.
