中厚板多层多道焊视觉测量与工艺规划
Visual measurement and process planning of multi-layer and multi-pass welding of medium and heavy plate
摘要
Abstract
Aiming at the weld channel measurement of multi-layer and multi-pass welding of medium-thick plate,the method of adaptive fine-tuning of the weld gun position using the fusion of information from weld seam detection and visual measurement of weld channel dimensions is proposed.Firstly,based on the structured optical vision sensor system,the weld seam images are acquired,and the weld seam feature information is extracted based on typical image processing algorithms combined with FROSAC extraction algorithm.The number of layers,the process parameters of each weld channel and the offset of the welding torch are determined based on the information of the weld seam characteristics,and the multi-layer and multi-pass welding process planning is completed.Finally,based on the robot welding vision system built on the 12 mm-base material for V-bevel multi-layer and multi-pass welding test,the results show that the method under the bevel fill well,the average measurement error of the weld channel size is less than 0.2 mm,meeting the needs of multi-layer and multi-pass welding industrial applications.关键词
