    • PROBLEM TO BE SOLVED: To provide a welding skill evaluation device which enables the detailed knowledge of a molten pool to be obtained through welding training under the visual observation of the molten pool as an image to thereby enable welding skill to be improved in a shorter period of time, and to provide a weld zone quality evaluation device which enables a welding work to be performed while the quality (complete penetration and incomplete penetration on the course of welding) of a weld zone is detected in real time during welding.SOLUTION: The welding skill evaluation device includes: a molten pool observation camera that observes a torch behavior and a molten pool surface behavior; a penetration bead observation camera that moves integrally with the molten pool observation camera and measures the molten state of the reverse side of the molten pool; a torch camera that is mounted to a welding torch and monitors a molten state and an arc state; a whole behavior photographing camera that photographes the posture of a welder; a monitor that displays images captured by these four cameras together with a welding current/voltage signal; a storage unit that stores and analyzes image information taken by the four cameras together with the welding current/voltage signal obtained from a welding current/welding voltage measurement unit; and a welding face shield to which a small monitor for displaying any of the images captured by the four cameras is attached.
    • 要解决的问题:提供一种焊接技术评估装置,其能够通过在熔池的目视观察下的焊接训练来获得熔池的详细知识,从而能够提高焊接技能 并且提供焊接区质量评估装置,其能够在焊接期间实时检测焊接区域的质量(焊接过程中的完全穿透和不完全穿透)的同时进行焊接工作。 焊接技术评估装置包括:观察火炬行为和熔池表面行为的熔池观察照相机; 与熔池观察摄像机一体地移动并测量熔池的相反侧的熔融状态的穿透珠观察照相机; 一个安装在焊炬上并监测熔融状态和电弧状态的火炬照相机; 拍摄焊工姿势的整体行为拍摄相机; 显示器,显示由这四个摄像头捕获的图像以及焊接电流/电压信号; 存储单元,其与由焊接电流/焊接电压测量单元获得的焊接电流/电压信号一起存储和分析由四个摄像机拍摄的图像信息; 以及焊接面罩,附接有用于显示由四个摄像机捕获的任何图像的小监视器。 版权所有(C)2013,JPO&INPIT
