Nuclear fuel rod end plug welding seam detection device

The invention belongs to the technical field of nuclear power, and particularly relates to a nuclear fuel rod end plug weld joint detection device. According to the nuclear fuel rod end plug welding seam detection device, the welding seam is scanned by utilizing the white light interference principle in a machine vision nondestructive inspection mode, the three-dimensional contour of the surface of the welding seam is obtained, and then the surface quality of the welding seam is judged through an algorithm. A linear array color camera is used for carrying out color image acquisition on a welding seam, and then the oxidation degree of the welding seam surface is judged through an algorithm. In this way, automation of weld surface detection is achieved, the detection efficiency is improved, the error risk caused by fatigue of human eyes due to long-term work is avoided, and the detection accuracy is improved. 本公开属于核电技术领域，具体涉及一种核燃料棒端塞焊缝检测装置。本公开的核燃料棒端塞焊缝检测装置通过机器视觉无损检查方式，利用白光干涉的原理对焊缝进行扫描，得到焊缝表面三维轮廓，再由算法判断焊缝表面质量。利用
