Electric Resistance Brazing

This paper describes in general the equipment for and process of making brazed joints. The lead soldered joint has been in use for a long time and has done its work well but because of certain inherent weaknesses, it is slowly being replaced by the brazed joint. The electric brazing equipment is listed and a short description of it given. The preparation of various sizes and shapes of work is taken up in detail and a short discussion of the different types of joints is given. Three kinds of brazing mediums are discussed and applications of each are mentioned. A description of the actual brazing process follows and the paper is concluded with a list of advantages of the brazed joint over the lead-soldered joint, including: increased factor of safety, saving in time, reduced cost, reduced size, and increased accessibility of joints for inspection.
