Abstract

PURPOSE: Two magnetic paths are formed holding a magnet between, and one path is almost a closed magnetic path containing the magnetic flux density detection element between while the other path is made open magnetic path at the area facing to the primary material to be welded. In this way, a sensor of a simple constitution can be obtained.
