WELD INSPECTION DEVICE AND WELD INSPECTION METHOD FOR BOILER WATER-COOLED WALL

WIPO Patent Application WO/2013/129411

A1

In order to provide a weld inspection device and a weld inspection method for a boiler water-cooled wall, with which breaches penetrating the welds between the water-cooled pipe and the fins in the boiler water-cooled wall and the welds between the fins can be detected quickly, reliably, and in a simple manner, the vacuum chamber (100) of a weld inspection device for a boiler water-cooled wall has: two side walls arranged so as to follow the shape of parallel water-cooled pipes; at least one end wall (114) arranged so as to intersect with the lengthwise direction of the parallel water-cooled pipes (10); side edge seal members for sealing between the edges of the side walls and the parallel water-cooled pipes (10); and end edge seal members (130) for sealing between the edge (138) of the end wall (114) and the parallel water-cooled pipes (10) and the fins (12). The edge (138) of the end wall (114) has a linear edge part (140) that follows the shape of the fins (12), and arch-shaped edge parts (142) that follow the shape of the parallel water-cooled pipes (10), and the end edge seal members (130) have a linear seal part (146) which are attached to the linear edge part (140), and arch-shaped seal parts (148) which are attached to the arch-shaped edge parts (142).
