Voltage distribution in the welding arc

APAPER by H. von Conrady entitled “Investigation of the Voltage distribution in the welding arc,” which was published in Elektroschweissung (volume 8, June 1937, pages 101–06; July 1937, pages 125–28) recently has been translated by Herman J. Munz and is being distributed by the welding research committee of The Engineering Foundation. The author (1) describes apparatus devised as a part of a research subject under investigation at the experimental station for welding technique of the Technical University of Berlin, Germany, for measuring the voltage drop in welding arcs carrying currents as large as 1,000 amperes; and (2) presents results of tests made with that apparatus.
