<P>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. <P>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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
