ようにしたことを特徴とする栓溶接検出器。The plug welding detector detects the plug welding point from outside the coating of the object to be measured, which is made by coating two plug-welded magnetic materials. An excitation coil is wound around each part that connects and supports adjacent comb-shaped parts, and the excitation coil is shared only with the detection coil of the comb-shaped part whose tip is located adjacent to the plug welding part. A plug welding detector characterized in that a plug welding location is detected by utilizing the electromotive force generated due to an imbalance in magnetic resistance based on a partial material difference, that is, a magnetic permeability difference, between two adjacent magnetic circuits.
