Abstract

PURPOSE:To enable a case band and bow part to be joined without requiring special skill by beforehand plating a blank material which is not good in conductivity to either of a case band body or a bow part, thence tentatively fixing these by means of resistance welding and performing brazing. CONSTITUTION:An alloy of Ni or the like which is less good in conductivity as compared to noble metals is applied on a case band 1 or bow 2 part by means of such as plating 3 and these are tentatively fixed by means of resistance welding, the case band 1 and the bow 2 are brazed by a nonoxidative furnace.
