摘　　要：为了推广应用高效高质量的窄间隙电弧焊方法,迫切需要解决焊缝跟踪问题。针对新型高速旋转电弧焊接工艺,建立了一种窄间隙焊缝跟踪电弧传感检测方法及系统,并分析了电弧传感器的工作特性。试验结果表明:通过计算电弧旋转中心前点两侧一定区域内电弧电流(或电压)信号的积分差,旋转电弧传感系统能够有效地检测出焊缝偏差,其传感检测灵敏度受电弧电信号积分域和被检电信号种类(电弧电流或电压)等影响。To apply practically the NGW（ narrow gap arc welding） process of high efficiency and high quality in manufacturing industries, it is very necessary to solve the problem of NGW seam tracking. This paper presents an arc sensing detection approach and its system for high-speed rotation arc NGW seam tracking, and investigates the characteristics of the arc sensor. Experimental results show that the arc sensing system developed can effectively detect out seam deviation by finding the integral margin of arc current （ or voltage） signal in some area of both sides around the centre of arc rotation, and its sensitivity varies with the type and integral range of the arc electrical signal detected.
