摘要:研发了一套轨道车辆铝合金车体自动焊缝在线视频监控的系统,实现了焊接操作人员通过观察实时视频进行焊接过程监控。焊接时,安装在焊枪的摄像头可以实时对焊接电弧位置、坡口情况进行监控,1套自动焊接系统的2支焊枪作业内容同时显示在1个即时显示器上,只需1名焊接操作工人观察即时显示器即可实时监控焊接过程,降低了人员需求。通过针对性解决焊接过程中的电磁干扰、弧光、高温、飞溅等问题,提升监控质量,焊接操作人员不需近距离观察电弧,降低了劳动强度,改善了工作环境,提升了焊接自动化水平。

Abstract:In this paper, an on-line video monitoring system for automatic welding seam of aluminum alloy car body of railway vehicle was developed, which could make welding operators monitor the welding process by observing real-time video. When welding, the cameras installed in the welding torch can monitor the position of welding arc and groove in real time. Two sets of welding guns for one automatic welding system are displayed on an instant display and just one welding operator can monitor the welding process in real time by observing the instant display, which reduces personnel demand. Monitoring quality is improved by solving the welding process of electromagnetic interference, arc, high temperature, splash and so on. The welding operator does not need to observe the arc at close range, which reduces the labor intensity, improves the working environment, and improves the welding automation level.
