Development of a narrow gap welding experiment system for oscillating arc sensing

  • 摘要: 为了提高窄间隙焊接摆动电弧传感的精度和可靠性,研究电弧到窄间隙坡口侧壁的距离对电弧传感特征参数的影响规律,通过高精度激光位移传感器测量焊枪相对于坡口中心的位置,基于TMS320F2812和Labview软件,开发了一种能同步采集电弧图像、焊接电压、焊接电流和焊枪摆动位置四路信号的电弧传感试验系统. 采用P-GMAW的焊接方式对开发的试验系统进行测试,结果表明,该系统可靠有效,为深入研究窄间隙摆动电弧传感特征奠定了必要的基础.

     

    Abstract: In order to improve the precision and reliability of welding arc sensor in narrow gap, as well as to research the principle of arc sensor characteristic parameters influenced by the distance between welding torch and the side wall, by measuring the torch position using high precision laser displacement sensor, an experiment system for swing arc sensor which can simultaneously acquire welding voltage, welding current, welding torch swing position and arc image four signals was developed based on TMS320F2812 and Labview. Experiment was carried out by the welding method of P-GMAW. It was proved by the experiment that the established system is reliable and effective. The system has laid the necessary foundation for the further study of the characteristics of the narrow gap oscillating arc sensing.
