Abstract

High cycle fatigue tests were performed on two strength categories of high strength steels, on quenched and tempered (S690 and S960) and thermomechanical (S960) types, on base materials and their gas metal arc welded joints, and on different matching conditions. The planning and optimization of welding technologies based on investigations under cyclic loading conditions were built upon a large number of investigations and statistical evaluation of the test results. Statistical approach was already applied during the preparation of the investigations, which have been allowed the expansion of the scope of the results and the increasing of their reliability. The article demonstrates and evaluates the results comparing with each other and with literary data.
