Beschreibung
Zusammenfassung:	Method and apparatus for nondestructive testing of the joint quality of fastened workpiece joints whereby the apparatus comprises a device (12) for heating a first workpiece (14) that is joined to a second workpiece (16), and a device (18) for optical measurement of a heat distribution, whereby the device for heating is an inductor (28) which is capable of producing a magnetic field (38) that acts on the first workpiece. L'invention concerne un procédé et un appareil permettant d'effectuer des essais non destructifs de la qualité des joints de pièces fixés. Cet appareil comprend un dispositif (12) qui permet de chauffer une première pièce (14) assemblée à une seconde pièce (16) et un dispositif (18) afin de mesurer optiquement la distribution de la chaleur. Le dispositif de chauffage est une bobine d'induction (28) qui est capable de produire un champ magnétique (38) agissant sur la première pièce.
