Abstract:
A method of laser welding a planar metal surface to a cylindrical metal surface, comprising:placing a planar metal surface into approximate contact with a cylindrical metal surface to form a juncture area to be welded, said planar metal surface and said cylindrical metal surface thereby forming an acute angle of contact, wherein said planar metal surface is made from a reflective metal selected from copper, copper alloys, aluminum and aluminum alloys and said cylindrical metal surface is made from a reflective metal selected from copper, copper alloys, aluminum and aluminum alloys; andfocusing a laser beam through the acute angle of contact at the juncture area to be welded, said laser beam heating the juncture area to a welding temperature thereby causing welding to occur between said planar metal surface and said cylindrical metal surface.
