Process control of nickel plate butt plasma arc welding based on PLC

  • 摘要: 为了实现等离子弧焊过程自动化控制,文中根据等离子焊接工艺对控制系统的要求,设计了以欧姆龙CP1H型PLC为控制运算核心结合触摸屏人机界面技术的控制系统。分析了等离子弧焊过程的特点,以及控制核心PLC在焊接过程的控制对象及控制时序。系统选用两台独立的焊接电源作为维弧和主弧电源,增强了系统的稳定性和抗干扰能力,选用RS-485进行PLC与触摸屏的数据传输,对相应焊接参数进行集中化控制调节。选用Easy Builder 8000设计软件构建了触摸屏人机操作界面,系统的介绍了整个系统的组成及相互关系。最后采用不填丝熔焊和ERNi-1焊丝作为填充材料两种焊接工艺,对6 mm厚度的N6镍板进行对接工艺试焊,焊缝成形良好,系统运行安全可靠,并具有较高的可维护性,实现了等离子弧焊过程的自动控制。
    Abstract: In order to realize automatic control of plasma arc welding process, the control system using the OMRON CP1H PLC as the core combined with touch screen was designed in accordance with the plasma arc welding requirements in the paper. Characteristics of plasma arc welding process, together with the control object and control sequence of the core PLC in the welding process were analyzed. Two independent welding power sources were selected as pilot arc and main arc power sources to enhance the stability and anti-interference ability of the system. RS-485 was used for data transmission between PLC and touch screen, and centralized control and adjustment of corresponding welding parameters was carried out. The human-machine interface of touch screen was constructed with Easy Builder 8000 design software and the composition and relationship of the whole system was systematically introduced. Finally, two welding processes, plasma welding without filler wire and with ERNi-1 welding wire were used as the filler material to butt weld N6 nickel plate with 6 mm thickness. The weld formed well. The system ran safely and reliably and had high maintainability. It realized automatic control of plasma arc welding process.
