Abstract

A welding material in positioned in electrically conductive relation between exterior surface portions of first and second weldable members, such as hydroformed tubes, at a location where the first and second weldable members are to be joined. A welding device comprises first and second electrodes or conductive ends that extend along substantially the entire extent of first sides of the first and second weldable members, respectively. The first and second conductive ends include first and second concave recesses, which nest with the first and second weldable members, respectively. Electrical current is applied across the first and second weldable members by the nesting first and second conductive ends such that the applied current melts the welding material and thereby welds the exterior surface portions to one another. The welding device can be mounted on a robotic mechanism, which can move the welding device between first and second welding positions.
