Expert welders demonstrate the speed, flexibility and efficiency of the process on all types of joints. "Closeups of the arc and the molten steel show how the troublesome 'arc blow', so characteristic of direct current welding, is eliminated by the use of alternating current." Movie makers STORY OF ARC WELDING. USBurMines 1945 24min sd color loan 671 W sh-tr-c Sponsored by the Lincoln Electric Co. Previously titled "Magic Wand of Industry — Arc Welding" A simple yet complete description of the technique of arc welding Actual scenes in shipyards and plants, as well as drawings, depict the part played by each unit of the welding equipment in fusing metallic joints to make them in many cases far stronger than the metal itself. Because the fllm is designed for showing to all types of audiences, it covers the application of arc welding in many occupations, including shipbuilding, aircraft construction and maintenance, truck and automobile manufacture, track-repair work, pipeline construction, production of tanks, tank destroyers, bombs and the fabrication of huge units for hydroelectric power plants 521
