Electrical conductor connection and method of making same

An electrical conductor connection comprising:

• first and second aluminum conductor members each having first and second major opposed flat surfaces;
• said first and second aluminum conductor members being lapped with at least a portion of their second and first major flat surfaces, respectively, in contact with one another;
• and a fusion of aluminum joining said lapped first and second aluminum conductor members;
• said fusion of aluminum having a connection central portion fused to both said first and second aluminum conductor members, and first and second end portions;
• said first and second end portions being convexly cupped and extending outwardly past the first and second major flat surfaces of the first and second aluminum conductor members, respectively;
• said connecting central portion of the fusion of aluminum having a substantially rectangular configuration at the interface of the second and first major opposed flat surfaces of the first and second aluminum conductor members, respectively, wherein the sides of the connecting central portion of the fusion of aluminum extend between the first and second major opposed flat surfaces of the second aluminum conductor member to define a substantially rectangular shaped end portion such that a plane intermediate and parallel to said major opposed flat surfaces intersects a substantially rectangular shaped perimeter of the connecting central portion of the fusion of aluminum, and wherein the sides of the connecting central portion of the fusion of aluminum extend substantially conically between the second and first major flat opposed surfaces of the first aluminum conductor member to define a substantially circular shaped end portion such that multiple planes intermediate and parallel to said major opposed flat surfaces intersect at first substantially elliptical and then substantially circular shaped perimeters of decreasing diameters of the connecting central portion of the fusion of aluminum, proceeding in a direction away from the interface of said second and first major opposed flat surfaces of the first and second aluminum conductor members.
