用探傷装置。 An arm is swingably attached to a traveling trolley that can move along the non-magnetic welded part where one and the other magnetic metal base materials are welded, and a flaw detection sensor with a permanent magnet as the sensor core is attached to the tip of the arm. , the arm is swung in the direction of the non-magnetic weld until it balances with the attraction force of the flaw detection sensor to the magnetic metal base material, and the flaw detection sensor is moved to the boundary between the non-magnetic weld and the magnetic metal base material. A flaw detection device for a weld boundary line, characterized in that a balance spring positioned on a line is interposed between the traveling carriage and the arm.
