(54)Method for fusing insulated wires, and fused wires produced by such method


(57) A method for fusing a pair of insulated wires (22a,22b) to one another, and a fused wire (20) made by such method, in which the combined or major diameter (D3) of the fused wire (20) equals, or very closely matches, the sum of the diameters (D1,D2) of the individual wires (22a,22b) prior to fusion. In the present method, a pair of wires (22a,22b), each having a coating (26a,26b) of insulation that is substantially fully cured, are brought into close abutting contact with one another along a line contact, and thereafter pass through a heating device which heats the coatings above their a thermal transition point of at least one of the pair of wires to fuse the coatings of the wires together along the line contact.
