摘　　要：针对大型长输管道(直径≥1 200mm)现场施工条件下对接环形焊缝焊接精度要求高、作业环境恶劣等问题,采用机器视觉、弧压跟踪、倾角检测技术使焊接专用机器人自主跟踪并规划焊接路径,自动调整弧压、电流等焊接参数,实现大型长输管道环焊缝全位置自动焊接。经实际应用表明,可显著提高焊接质量和效率,减轻操作人员劳动强度,减少可能的事故性损失。Aiming at the problems of high welding accuracy and harsh working environment of long distance pipeline(diameter ≥1 200mm), machine vision, arc voltage tracking and inclination detection technology are used to make the special welding robot track and plan the welding path independently, and automatically adjust the arc voltage, current and other welding parameters, so as to realize the automatic welding of the whole position of long distance pipeline. The practical application of automatic pipeline welding system based on machine vision shows that it can improve the welding quality and efficiency, reduce the working intensity of personnel and the possible accident loss.
