Abstract
Welding apparatus for making metal honeycomb core panels by welding together preformed corrugated metal strips is disclosed. The assembled portion of the core panel is positioned by vertical finger electrodes on a horizontal base with the core panel workpiece end located along the line of a welding station extending across the base. The finger electrodes are arranged in two rows extending parallel to the welding station line, one row being insertable into the honeycomb core from above and the other being insertable into the core from below, each row also being movable from a first workpiece engaging position to a second welding position with one edge thereof along a welding station line. Welding heads, each including a welding element, are movable to and from the welding station. A corrugated metal strip is detachably held onto and carried to the welding station by the welding heads. The strip is positioned at the welding station with its outer apices and those apices on the workpiece end of the core panel engaging each other at nodes along the welding station line. The welding elements are elongated members having edge faces, the profiles of which register with the strip inner api…
