[en] A description is given of the development of the procedures for brazing the conductor splice joint and subsequent nondestructive testing of it. A series of pre-production conductor samples have been brazed to evaluate the procedures developed. The final evaluation of these samples is a destructive test to determine the mechanical strength properties of the braze joint. These procedures which have been tempered by the experience gained preparing and testing pre-production conductor samples will be applied to the production winding of the toroidal coils
