Study on a Pipe Welding Robot based on Laser Vision Sensing

A type of pipe welding robot system was studied. It recognizes and tracks the groove in two dimensions using one laser visual sensor. When the first layer seam is real-time tracked and welded, the groove information is memorized by robot, and the work of teaching robot is completed at the same time. Experimental results verify that the welding seam tracking can meet the needs of the automatization of pipe welding process.
