Abstract

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).
