Abstract

A welding assembly including a welding gun for providing spaced welds on opposite sides of members being welded. The welding gun includes two welding tips so that both welds can be formed without moving the gun or the members relative to each other. Preferably one weld tip is connected to a force applying mechanism such as a hydraulic cylinder to clamp the members together and improve the connection between the weld tips and the members. The weld gun can be used for making one or two welds while in the engaged position around the members being welded. Also, one of the weld tips can be replaced with a support that merely provides the force applying function.
