HAND WELDING ANALYZER AND HAND WELDING TORCH-INTEGRATED TYPE MONITORING CAMERA APPLICABLE TO THE ANALYZER

PROBLEM TO BE SOLVED: To provide a hand welding analyzer that images the behavior of a TIG hand welding operation and that evaluates welding skill based on the feature amount extracted from the image, and also to provide a hand welding torch integrated type monitoring camera that is applicable to the analyzer. SOLUTION: The hand welding analyzer analyzes and processes the image information around a molten pool during the welding that is imaged by the monitoring camera installed in the periphery of the target hand welding operation. The analyzer is equipped with a hand welder integrated type image pickup unit 1 that integrally connects the monitoring camera 2 with the hand welding torch 3, an image data recorder 8 that processes and records the digital signals of the image from the image pickup unit, a data processor 9 that processes the recorded image information as data, and a display device 10 that displays the information so processed.
