Fully articulated automatic welding robot, its position and attitude are all realized by rotary motion, so it has the advantages of compact mechanism, good flexibility, small footprint, large workspace, and can obtain high end operator line speed, etc. At present, part of it is welded by using the pre-set program, which can't do the intelligent tracking, and the precision is not high.

The use of supporting sensors applied to robotic welding automatic tracking system, online real-time detection of weld, welding automation and intelligence, robot welding seam tracking, welding seam positioning
