摘　　要：焊接电流波形对焊接过程稳定性和焊缝质量起着决定性的作用。在此以M SP430单片机为控制核心,VK65液晶显示器作为人机交互窗口开发了多功能TIG焊控制器。该控制器可以通过按键及数字接触式编码器配合中文菜单完成所有TIG焊的程序参数、焊接电流的波形参数的设置,同时具有焊接工艺参数记录,焊接波形显示,与上位机通信的能力。将该控制器应用到W SE系列焊机,可以方便地输出变极性、低频脉冲调制、高频脉冲调制等多种波形及其任意组合。试验表明,采用该控制器的W SE焊机操作简单,焊接工艺性能优良。The stability of welding process and the quality of welding seam are decisively affected by the welding current wave.A multifunctional TIG controller is developed adopting SCM MSP430 and VK65 liquid crystal display.All of the TIG welding process parameters and current wave parameters can be set through the Chinese menus by using key and digital contacting encoder.At the same time,welding process parameters can be recorded,welding wave can be displayed,and it can be communicated with other controllers.It is convenient to output the waves of variable polarity,low frequency modulated pulse,high frequency modulated pulse etc,and the combination of the above waves.The experiment shous that the WSE welder is easy to operate and to get good seam by adopting this controller.
