TLDR
In this article, an automatic arc welding apparatus consisting of a welding carriage movable supported by a horizontal guide beam, which carriage supports a plurality of arc welding heads for forming welds on a generally horizontally disposed work piece, wherein the welds may be of compound curvature.Abstract:
Automatic arc welding apparatus in accordance with the present invention comprises a welding carriage movably supported by a horizontal guide beam, which carriage supports a plurality of arc welding heads for forming welds on a generally horizontally disposed work piece, wherein the welds may be of compound curvature. The welding head mechanisms are supported by compound connection apparatus that defines three interrelated axes that are cooperatively related to enable an electrode support to which welding wire electrode is automatically fed to precisely follow a joint of compound configuration that is established between angularly related portions of the work piece. Additionally, the welding head mechanisms are movable both vertically and laterally to facilitate proper positioning thereof to the work piece being welded.read more
