BEAD APPEARANCE INSPECTION DEVICE, BEAD APPEARANCE INSPECTION METHOD, BEAD APPEARANCE INSPECTION PROGRAM AND BEAD APPEARANCE INSPECTION SYSTEM

To shorten inspection time and increase efficiency of bead appearance inspection when bead appearance inspection of a workpiece manufactured by final welding has defects.SOLUTION: A bead appearance inspection device includes: an acquisition part for acquiring input data concerning a weld bead; a storage part for storing a first determination reference and a second determination reference used in inspection of defects of a weld bead; a first determination part for executing first inspection determination for the weld bead, and determines whether or not a first inspection result acquired by the first inspection determination satisfies the first determination reference; and k pieces of second determination parts for executing second inspection determination for the weld bead, and determining whether or not a second inspection result acquired by the second inspection determination satisfies a second determination reference. When either the first determination part or k pieces of the second determination parts detect defects, the other of the first determination part or k pieces of the second determination parts cancel current executed processing.SELECTED DRAWING: Figure 7 【課題】本溶接により生産されたワークのビード外観検査に不良がある場合の検査時間を短縮し、ビード外観検査の効率を高める。【解決手段】ビード外観検査装置は、溶接ビードに関する入力データを取得する取得部と、溶接ビードの不良の検査に用いる第１判定基準および第２判定基準を記憶する記憶部と、溶接ビードに対する第１検査判定を実行し、第１検査判定により取得された第１検査結果が第１判定基準を満たすか否かを判定する第１判定部と、溶接ビードに対する第２検査判定を実行し、第２検査判定により取得された第２検査結果が第２判定基準を満たすか否かを判定するｋ個の第２判定部と、を備え、第１判定部およびｋ個の第２判定部のうちいずれか一方が不良を検出した場合、第１判定部およびｋ個の第２判定部のうちの他方は、現行実行中の処理を中止する。【選択図】図７
