Abstract

667,400. Brazing. GENERAL MOTORS CORPORATION. June 8, 1949, No. 15260/49. Drawings to Specification. Class 83 (iv). [Also in Group XI] Before passing metallic tubing formed from strip metal into a brazing furnace such as is described in Specification 527,093, the tubing is preheated by passing it through an apparatus (see Group XI) providing a non-oxidizing atmosphere between spaced electrodes and arranged such that the tube is heated by current passing lengthwise through it. Specification 531,215 also is referred to.
