The multi-layer and multi-pass welding (MLMPW) process plays an important roll in the field of medium-thick plate automatic welding. To solve the problem of the robot self-adapting to the deviation of the weld position and the groove size due to the influence of the workpiece positioning and the welding deformation in MLMPW. a novel method based on the laser vision system to correct t... https://pipingrockers.shop/product-category/dna/
