Abstract

L'invention concerne un dispositif pour accorder la fréquence de résonance des résonateurs. Il est caractérisé en ce que la cavité intérieure du résonateur comporte un insert en une matière ferromagnétique situé au moins près des parties où l'intensité du champ magnétique est à un maximum quand le résonateur est alimenté avec un courant ayant la fréquence voulue et en ce que ledit insert en matière ferromagnétique est conçu de façon à pouvoir être polarisé par des moyens appropries tels que des bobines d'électro-aimants. Application notamment à la soudure des feuilles minces par création de chaleur.
