Patent ID: 8466386

Claim:
A method of repairing a metallic structure having a first metallic member, a second metallic member and an adhesive layer between the first and second metallic members, wherein the first metallic member and the second metallic member are bonded to the adhesive layer, the method comprising: forming a hole in at least one of the first metallic member and second metallic member, wherein said hole is sufficiently configured to receive a slug; wherein said hole extends through the adhesive layer bonding the first metallic member to the second metallic member; inserting said slug into said hole and through the adhesive layer to define a first interface between a first portion of the slug and the first metallic member, a second interface between a second portion of the slug and the second metallic member, and a third interface between a third portion of the slug and the adhesive layer; passing electrical current through said slug, wherein said electrical current is of sufficient intensity to form a first weld at the first interface between the first metallic member and said slug and to form a second weld at the second interface between the second metallic member and said slug, thereby securing the first metallic member with respect to the second metallic member; and wherein the first weld and the second weld are separated by the third interface after forming the first and second welds.
