【摘要】：針對常規(guī)雙絲旁路耦合電弧熔化極氣體保護焊(GMAW)的控制過程較復(fù)雜、焊接成本較高等問題,提出了采用單電源實現(xiàn)雙絲旁路耦合電弧GMAW的方法,并設(shè)計了采用快速原型技術(shù)的實驗系統(tǒng).同時,進行了大量焊接工藝實驗.實驗結(jié)果表明:采用單電源的雙絲旁路耦合電弧GMAW可以穩(wěn)定焊接,但相對于雙電源的雙絲旁路耦合電弧GMAW其穩(wěn)定工作區(qū)間更窄;通過調(diào)節(jié)旁路送絲速度快慢的焊接工藝實驗,分別找到了在主路電流為300、350、400、450、500、550A時旁路送絲速度的穩(wěn)定工藝區(qū)間.
[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.
