AUTOMATIC METALLIC ARC WELDING

An automatic metallic arc welding machine, which was designed and manufactured by Metropolitan-Vickers Electrical Co., Ltd., consists of a motor-operated, rotating jig; on to which the folder U-shaped end of the wagon body is located and clamped together with the stiffening bars, which are also located by clamps. Long straight butt or fillet welds, whether longitudinal or circumferential, are obvious choices for automatic welding. A typical application for the use of continuous automatic welding is that of welding tee or angle stiffener bars on railway mineral wagons. The estimated hand-welding time for each 40 in. pass was six minutes, and the automatic welding time five minutes. In the case of an axlebox made up of 1/4 in. thick pressed U-shaped section forming the bottom and sides and involving 13 welds, a comparison shows a saving of one minute with automatic welding.
