    R & D of Automatic Tracking System for Gas Shielded Welding Gun of Straight Seam Pre-welding Machine

    • 摘要: 介绍了一种直缝预焊机气体保护焊枪自动跟踪系统。简述了该自动跟踪系统的总体软硬件架构,以及该系统的软件原始图像采集及显示模块、运行报警模块、外设逻辑给定模块,重点分析弧光图像处理及特征点捕捉模块、坡口参数及偏移量计算模块。实践表明:该自动跟踪系统运行稳定,能较好地自动控制预焊枪跟随焊缝中心,并表现出较强的抗气体保护焊弧光干扰的特性。

       

      Abstract: Described here in the paper is a automatic tracking system for the gas-shielded welding gun of the straightseam pre-welding machine,briefing such main aspects as configuration of the general hardware and software,the modules of the system for such functions as software origin image acquisition,running alarming,and peripheral logic-presetting.Focused on analyzing modules for arc image processing and feature point-capturing,and calculating of bevel parameters and offset. The actual operation of the system demonstrates that the tracking system runs consistently,being capable of properly and automatically controlling the pre-welding gun to make it follow the weld seam center,and showing the feature of well resisting the gas shielded welding arc interference.
