Abstract :
During the past 10 years the committee on welded rail joints appointed by the American Bureau of Welding and the American Transit Engineering Association, has been engaged, with the cooperation of the U.S. Bureau of Standards, upon a study of welded rail joints. The purpose of the extensive investigation undertaken has been the improvement and standardization of methods of making these joints. The tests included conductivity, tensile, bend, drop, repeated impact and shear tests, as well as numerous metallurgical and miscellaneous investigations. All types of welded joints commercially used were tested and examined by the committee.
