Abstract A method of electron beam welding a patch into an aperture in a finished component to form an assembly. A patch is inserted into a corresponding aperture in a component, excess material being provided on the face of the patch and/or the component to be presented to the electron beam. The electron beam is directed so that it first impinges on the excess material, and then the component is moved relative to the beam so that the beam impinges on and then follows the interface between the component and the patch. Thus, the patch is welded to the component around the periphery of the patch. The component is then moved relative to the beam so that the beam again impinges on the excess material, the action of the beam is then stopped, and the excess material is machined away.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
A method of electron beam welding a patch into an aperture in a component to form an assembly including the steps of: inserting the patch into the aperture of the component; providing excess material on the surface of the assembly which at least in part is contiguous with the innerface between the patch and component; directing the electron beam so that it first impinges on said excess material; imparting relative movement between the beam and the assembly so that the beam intersects said innerface and said contiguous part and follows the innerface between the component and the patch to effect a weld; terminating the action of the beam on said excess material; and machining away said excess material from said assembly.

Claim 3
Dependent Claim
19 words
A method of claim 1 in which the excess material is disposed on said patch and is integral therewith.
Claim 4
Dependent Claim
24 words
A method as claimed in claim 1 in which the excess material is provided in the form of a mask arranged on the assembly.
Claim 5
Dependent Claim
20 words
A method as claimed in claim 3 in which the mask is disposed on the patch portion of the assembly.
Claim 6
Dependent Claim
20 words
A method as claimed in claim 3 in which the mask is disposed on the component portion of the assembly.
