| titleOfInvention | Methods for making edgelay thermostatic bimetals |
| abstract | A method for making an edgelay thermostatic bimetal is disclosed in which two relatively long and thin strips of metal having the same coefficient of thermal expansion are continuously advanced into edgewise abutting engagement with respective lateral edges of a third, central strip of metal of widely different coefficient of thermal expansion. The pairs of abutting strip edges thus formed are then welded together substantially simultaneously as by tungsten inert gas shielded welding or the like. The simultaneous nature of the weld formation results in substantially uniform heating of all three of the strip materials at the weld location, thereby to avoid the excessive warping and twisting of the resulting, welded composite material which might otherwise occur due to the wide difference in coefficient of thermal expansion between the central strip material and the other strip materials. After cooling of the welded composite, the composite material is slit longitudinally through the central strip of metal to divide the composite into two substantially identical edgelay bimetals each embodying a strip element of relatively low coefficient of thermal expansion and a strip element of relatively high coefficient of thermal expansion. The disclosed apparatus includes means for advancing the three strips of metal in edgewise abutting relation to each other over the periphery of a large metal roll which has two circumferential grooves formed therein, the grooves being arranged to be aligned with pairs of abutting strip edges as the strips are advanced over the roll. A pair of welding means are disposed in closely spaced relation to each other to weld respective pairs of abutting strip edges together substantially simultaneously while the strip edges are positioned over the roll grooves, the large metal roll serving to rapidly conduct heat away from the strips as they are welded to minimize the width of the weld formed between each pair of the metal strips. In a preferred embodiment of the apparatus, additional rolls engage other surfaces of the metal strips being welded to conduct additional heat away from the strips for further reducing the widths of the welds formed between the strips. |
