Development of a High Speed Rotating Arc Sensor System for Tracking Complicate Curved Fillet Welding Lines 复杂的弯曲角焊缝跟踪高速旋转电弧传感器系统的开发 Gun-You Lee Myung-Suck Oh and Sang-Bong Kim ABSTRACT This paper presents development of a high speed rotating arc sensor system using a microprocessor based controller with tracking function for a complicate curved fillet welding line. The welding tip connected to the torch body is eccentrically positioned from the centerline of the torch. The area during one rotating cycle is divided into 4 regions of front, rear, right and left in welding direction of the torch tip to determine the horizontal deviation between the welding seam and the torch position. The average value at each region is calculated using the regional current values and a low pass filter incorporated with the moving average method is implemented. The effectiveness of the developed system is proven through the experimental results for several kinds of complicate curved fillet welding lines. 摘要 本文提出了一个基于微处理器的控制器和复杂弯曲的角焊缝跟踪功能的高速旋转电弧传感器系统的使用。焊接头连接到所述的焊炬本体的中心线。在一个旋转周期为4个区域，前、后、左、右的焊接方向，以确定水平焊缝及焊枪位置之间的偏差。在每一个区域的平均值是使用区域的电流值计算，并与移动平均法注册成立的低通滤波器的实现。开发系统的有效性通过实验结果证明了几种复杂弯曲角焊线。 Key Words: Arc sensor, GMAW(Gas Metal Arc Welding), Seam tracking, Welding automation 关键词：电弧传感器，气体保护焊，焊缝跟踪，焊接自动化 Introduction Today, a welding process is being strongly encouraged to improve quality, productivity and labor conditions. In the area of shipbuilding construction, an automated welding process is ultimately necessary, since welding sites are spatially enclosed by floors and girders, and welders are exposed to hostile working conditions. So, a welding process is a difficult manufacturing process because of insufficiency of skilled workers as well as decline of productivity and requirement of continuous and stable quality control. Robotic welding is widely adapted in several fields of welding shops for improvement of welding efficiency and liberating operators from severe
