| 162 | COMPOSITE METAL PANEL. | EP88907182 | 1988-08-05 | EP0371070A4 | 1990-06-26 | HEUMILLER DONALD LES |
| A composite metal panel (10), particularly for use in constructing railroad passenger cars, comprises a sheet metal outer component (11) resistance-welded to the lands, or ridges (15), of an underlying corrugated metal component (12). Also disclosed is a method of fabricating such a panel, including laying the outer component (11) on a cooled copper bed, which forms one electrode, and placing the corrugated component (12) on top of the outer component. A welding apparatus electrode is applied to the rear surface of the corrugated component at spaced-apart locations (X), and current is passed between the two electrodes to thereby resistance-weld the lands, or ridges, of the corrugated component to the outer component at the spaced-apart locations. | ||||||
