Abstract
A method is disclosed for brazing components in a structure using a gap setting surface and brazing foil as brazing filler between the parts in order to form uniform joints having optimal dimensions, shape and strength. The components are assembled in an unconstrained stack, and a controlled load is applied to the top of the stack. The stack is then heated to a temperature at which the brazing foil melts and reacts with the components to form the joints. The stack is cooled resulting in a brazed structure having the desired dimension.
Claims20
A method for brazing components, the method comprising:
- providing an interlayer in foil form;
- providing a gap setting surface;
- assembling the components in a stack consisting of gap setting surface and the components separated by said interlayer foil, whereby the stack is unconstrained from movement in the vertical direction and constrained from movement in the lateral direction;
- and
- applying a controlled load on top of said stack acting in a vertical direction.

An X-ray tube comprising:
- an anode assembly configured to emit X-ray beams;
- and
- a cathode assembly configured to emit electrons towards the anode assembly, wherein the cathode assembly comprises:
- an insulator comprising a top surface and a bottom surface;
- a cathode element comprising a top surface and a bottom surface;
- and
- a gap setting surface positioned between the cathode element and the insulator, whereby the distance between the cathode element and the insulator is set by the gap setting surface.
