Abstract :
On September 6, 1933, the American Standards Association gave its formal approval to the standards for “Resistance Welding Apparatus” and “Electric Arc Welding Apparatus.” The approved standards are revisions of former A.I.E.E. standards Nos. 38 and 39, these revisions having been developed by a sectional committee working under the rules of procedure of the A.S.A. It is expected to issue the revised editions in the near future.
