The power-distribution problem in arc welding

THE extent to which arc welding has contributed to the shipbuilding program is well known. The consequent expansion of welding in shipyards resulted in various problems: the training of operators, production of the materials used, and by no means least, the development of satisfactory power-distribution systems. It is the intent of this paper to discuss briefly the general principles of power distribution for arc welding and to illustrate the application of these principles in the provision of an adequate, flexible, and economical distribution system in a typical shipyard. Although many conditions in shipbuilding are peculiar to the industry, it is believed that similar reasoning can be applied to any metal-fabricating plant making use of arc welding on a like scale.
