ABSTRACT:
An apparatus for detecting a nugget for spot welding utilizing the magnetic after-effect which is generated when a variation in the magnetic field is applied to a nugget. The apparatus includes a driving coil, which applies a magnetic field variation to a spot-welded nugget, and a magnetism sensing element, which detects variations in magnetic flux density arising in the vicinity of the nugget as a result of the magnetic field variation. The magnetism sensing elements may be installed in an array form so as to face the nugget and the area around the nugget.
