ABSTRACT. The article processes issue of strength of cyclically loaded welded joints with a focus on fillet welds. The data for used steels and basic information were obtained at U.S. Steel Research Laboratory and from articles by Lehigh University and the University of Illinois in USA. The practical application of the solution is presented for crane car body to crawler connection.
