    Abstract: A method of forming a bonded assembly (10). The method comprises: providing at least first and second parts (12, 14) of an assembly (10) to be bonded; assembling the first and second parts (12, 14) in a required relative position to define a bond interface region therebetween; sealing part way along an edge (18) of the bond interface region using laser beam welding to define a cavity between the first and second parts (12, 14); in a vacuum environment, sealing the remainder of the edge (20) of the bond interface region using electron beam welding to form a fluid tight seal around the cavity; and applying heat and pressure to an external surface of the cavity to diffusion bond the first and second parts (12, 14) together.
