在激光焊接过程中存在众多干扰因素,为保证焊接质量,需要对激光焊进行质量控制.实现焊接质量控制的关键是表征焊接质量信息的获取,而焊接熔池和小孔包含丰富的焊接质量信息.针对不锈钢Nd:YAG激光焊,构建了同轴视觉检测系统,获得了熔池和小孔图像.根据熔池和小孔图像的特点,设计了图像处理算法,并分别针对熔池和小孔确定了搜索起始点和搜索准则.
在激光銲接過程中存在衆多榦擾因素,為保證銲接質量,需要對激光銲進行質量控製.實現銲接質量控製的關鍵是錶徵銲接質量信息的穫取,而銲接鎔池和小孔包含豐富的銲接質量信息.針對不鏽鋼Nd:YAG激光銲,構建瞭同軸視覺檢測繫統,穫得瞭鎔池和小孔圖像.根據鎔池和小孔圖像的特點,設計瞭圖像處理算法,併分彆針對鎔池和小孔確定瞭搜索起始點和搜索準則.

In order to obtain good welding quality,it is necessary to apply quality control because there are many influencing factors in laser welding process.The key to realize welding quality control is to obtain the quality information.Abundant weld quality information is contained in weld pool and keyhole.Aiming at Nd:YAG laser welding of stainless steel,a coaxial visual sensing system was constructed.The images of weld pool and keyhole were obtained.Based on the gray character of weld pool and keyhole in images,an image processing algorithm was designed.The search start point and search criteria of weld pool and keyhole edge were determined respectively.
