单电源双丝埋弧自动焊及其应用前景

Double Wire Automatic Submerged Arc Welding with Single Power and Its Application Prospect

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及丝间距,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。最后分析了这种埋弧焊方法的应用前景。

Double wire automatic submerged arc welding is a welding method with high melt applying speed rate,high welding speed,low heat input. It can be more sufficient adjustment to the forming of welded seam,fusion depth/ fusion width and dilution to change arrangement mode of wires and space between wires.It can be the same with submerged arc stack welding of anti grinding or anti corrosion surface required lower dilution rate and also fit for single pass or multi pass high speed submerged arc welding of all kinds of butt jointing,angle welding. It also describes the structure key points of this welding unit,indicates the rational configuration requirements of power and wire feeding unit and analyses the application prospect of this submerged arc welding method.
