Abstract
IN the February issue of Swiss Technics, a journal published by the Swiss Office for the Development of Trade (Zurich and Lausanne), which co-operates with the Swiss Association of Machinery Manufacturers, Zurich, there is an instructive account of a visit made to the Secheron Works at Geneva. These works have always been strictly limited to the construction of heavy electrical machinery and material. A few years ago, when the electrification of the chief Swiss railroads, to which the Secheron Works greatly contributed, drew to a close, new lines of manufacture were tuken up. Among these was the building of electric welding apparatus and the manufacture of the necessary electrodes. The Secheron alternating-current arc-welding apparatus has now almost everywhere replaced direct-current revolving units. For the welding of complicated parts ‘exotherme’ electrodes are almost universally employed; cut-out or stamped parts can be simply welded together by the melting of the electrode into the space left between them, thus forming a solid block as homogeneous as a foundry casting.
