    Abstract: A method of fabricating a truss core sandwich panel of the type including first and second face sheets secured on opposite sides of a corrugated sheet. The first face sheet is welded to one side of the corrugated sheet and the second face sheet is positioned in contact with the other side of the corrugated sheet. A conductive mandrel is positioned between the first face sheet and the corrugated sheet, the height of the mandrel being less than the distance between the first face sheet and the corrugated sheet by a predetermined amount. The first and second face sheets are positioned between opposed welding electrodes, with the mandrel being coplanar with the electrodes. A welding force is applied to the first and second face sheets by means of the electrodes, the force being sufficient to deflect the first face sheet into contact with the mandrel and to bring the mandrel into contact with the corrugated sheet to permit electrical continuity between the electrodes. The predetermined amount is such that the deflection of the first face sheet will not exceed the yield point of the material thereof. A current is passed between the first and second electrodes to weld the second face sheet to the corrugated sheet and the welding force is released. The mandrel is moved to a new location and the process is repeated.
