Abstract

Suivant ce procédé l'embout 24 emboîté dans la tige 10 comporte deux rainures 24 disposées en croix qui débouchent sur la face externe de la tige 10. Après mise sous vide de la cavité 16, par l'intermédiaire des rainures 24 la tige et la pièce de fond 12 sont réunies entre elles par soudage par faisceau électronique, ce qui assure simultanément l'obturation des rainures, en empêchant le risque que des impuretés agressives pénètrent dans la tige au cours de traitements ultérieurs.
