Abstract
A method of joining metal components having the steps of depositing adhesive material between the components and welding the components together via solid-state or fusion welding. The welds are spaced apart from the adhesive material and are produced so as to prevent exposure of the adhesive material to the welding. The two types of bonds (adhesive and welding) are produced in the components separated by time and space.
Claims20
An assembly of joined metal components comprising:
- a first component having an exposed surface and a first joint surface;
- a second component having a second joint surface abutting said first joint surface and at least one recess forming a space between the first joint surface and the second component;
- adhesive material completely filling the space formed by the at least one recess in the second component and the first joint surface of the first component, wherein the adhesive material is substantially enclosed within the at least one recess;
- and
- a fusion or solid state weld extending from said exposed surface into said second component at a portion of said second joint surface separate from said at least one recess containing said adhesive material filling;
- wherein said adhesive material is disposed to form a), b), or both a) and b), wherein a) is a barrier isolating the interface between the components from moisture or other corrosive materials;
- and b) is a reinforcing member to compensate for a reduction in the components mechanical properties caused by the welded region.

A method of joining metal components comprising the steps of:
- providing a first component having a first joint surface;
- providing a second component having a second joint surface and at least one recess;
- contacting the first joint surface of the first component with the second joint surface of the second component, wherein the at least one recess forms a space between the first joint surface of the first component and the second component;
- and
- in any order, fusion or solid state welding the first joint surface to a portion of the second joint surface that is separate from the at least one recess and completely filling the space between the first joint surface of the first component and the at least one recess of the second joint surface with an adhesive material,
- wherein said adhesive material is substantially enclosed within the at least one recess to form a), b), or both a) and b), wherein a) is a barrier isolating the interface between the components from moisture or other corrosive materials;
- and b) is a reinforcing member to compensate for a reduction in the components mechanical properties caused by the welded region.
