摘　　要：单电源双丝埋弧自动焊是一种高熔敷速率、高焊接速度、低热输入的埋弧焊方法。通过改变焊丝排列方式和丝间距,其焊缝成形、熔深/熔宽、稀释率可得到更充分的调节。既可适用于稀释率要求较低的耐磨或耐腐蚀表面的埋弧堆焊,亦可适用于各种对接、角接焊缝的单道或多道高速埋弧焊。简述了这种焊机的结构要点,指出了电源及送丝系统的合理配置要求。Single power source twin-wire submerged arc welding process is one of alternative methods of submerged arc welding with high deposition rate,high welding speed,but low heat inpot and energy consumption.By means of changing arrangment of twin-wire to welding line and distance between of twin-wire,The weld penetration shape,depth/width,and dilntion can be regular more sufficiently,so that can be used not only for wear-resistant or corrosion-resistant ,further more for various butt-or filter-weld with single-bead or multi-bead and high welding speed,finally,structure of the automatic SAW welding machine and consisting of the power source and wire feed system have been suggested in this paper.
