Abstract
PURPOSE:To easily and accurately inspect a leak in a welded zone by applying soap water over the welded zone where a closed space is formed and injecting air from the open end of the closed space. CONSTITUTION:The hermetically sealed weld zone 16 of a coating plate 10 is welded in a direction intersecting orthogonally with a seam weld zone 14 to form the closed space 18 of the coating plate 10 having the open end 20. Then the soap water is applied over the periphery of the welded zone 14 and air is injected into the closed space 18 by an air compressor from the open end 20 with specific pressure. If there is an unwelded part 22 which is a defective part, the injected air leaks from the part and a thin film of soap water forms a bubble 24, so the unwelded part is detected extremely easily and accurately.
