对称过渡阶段时间对双丝MIG焊的影响
Research on symmetrical transition time's effects on double-wire MIG welding
摘要
Abstract
A symmetrical transition waveform control process for double-wire MIG welding is proposed based on the current study,with considering the change of electromagnetic force between two wires.the effects of The availability of symmetrical transition and double-wire transition time Ts on welding quality are studied.The results show that it's helpful to improve the stability of the welding process while increasing the symmetry transition.Under the current experimental conditions,double-wire transition time Ts should not be lower than 1 ms, otherwise the advantages of symmetric transition control are unable to be realized.Double-wire transition time Ts should not be longer than the peak time, otherwise it will affect the weld quality and lower welding speed.During the transition time of 2-3 ms,waveforms are stable and weld quality is good.This results provide basic process data for symmetrical transition waveform control process and a new approach for waveform control of double-wire welding.关键词
