Real-time weld seam localization for electron beam welding based on secondary electrons

In this study, a real-time secondary electron-based weld seam localization method is proposed to improve the accuracy and reliability of weld seam localization during electron beam welding (EBW). By using secondary electron imaging technology, detailed image information of the weld area is acquired in real time and these images are analyzed to accurately locate the weld position. Compared with the traditional optical observation method, the secondary electron-based real-time weld seam localization method has the advantages of high real-time performance and accuracy, high automation and quantification, and strong resistance to environmental disturbances. The experimental results show that the method can effectively improve the welding quality and ensure the stability and consistency of the welding process.
