【摘要】：针对常规双丝旁路耦合电弧熔化极气体保护焊(GMAW)的控制过程较复杂、焊接成本较高等问题,提出了采用单电源实现双丝旁路耦合电弧GMAW的方法,并设计了采用快速原型技术的实验系统.同时,进行了大量焊接工艺实验.实验结果表明:采用单电源的双丝旁路耦合电弧GMAW可以稳定焊接,但相对于双电源的双丝旁路耦合电弧GMAW其稳定工作区间更窄;通过调节旁路送丝速度快慢的焊接工艺实验,分别找到了在主路电流为300、350、400、450、500、550A时旁路送丝速度的稳定工艺区间.
[Abstract]:In view of the complex control process and high welding cost of conventional double wire bypass arc coupled arc welding (GMAW), the method of using single power source to realize double wire bypass coupled arc GMAW is put forward. An experimental system using rapid prototyping technology is designed. At the same time, a large number of welding process experiments were carried out. The experimental results show that the double wire bypass coupling arc GMAW with single power supply can stabilize welding, but the stable working range of double wire bypass coupling arc GMAW is narrower than that of double wire bypass arc, and the welding process experiment of adjusting the speed of bypass wire feeding is carried out. The stable process range of bypass wire feeding speed is found when the main current is 300350400450500550A.
