摘　　要： 在本文的焊接规范下,对机器人四丝焊的不同相位的熔滴过渡进行了高速摄影分析.结果显示,前、后丝脉冲电流交替相位时,其电弧形态彼此间基本没有影响,呈现锥状;前、后丝脉冲电流同步相位时,其电弧彼此相互吸引,电弧向2个焊丝中间交汇集中;前、后丝脉冲电流随机相位时,其电弧时而同步,表现为彼此吸引,向2个焊丝中间集中,时而交替变化,电弧形态彼此间没有影响. Based on the high-speed photography,the effect of phase relations on droplet transfer and welding seam was analyzed.To each TCGMAW（Twin-wire Co-pool Gas-shielded Metal Arc Welding） torch at four-wire welding robot,under the descriptive welding parameters,when the phase relation of the front wire and the back wire was alternate,the arcs of the two wires had no effect on each other basically;the welding seam shaped very well.When the phase relation was synchronized,the arcs attracted each other and the two arcs centralized to the middle of the two wires;the humping bead was formed.When the phase relation was random,now and then the arcs synchronized and attracted each other,and at times the arcs changed alternately and had no effect on each other;the appearance quality of the welding seam was moderate.
