Abstracts

EN

Welding of different types of steel is fundamental proces for the production of car bodies. Fatigue degradation is still a significant factor in long-term use. Current trends welding and combinations of different types of steel are used. The specific form of the course of fatigue in the welded joints is followed. Test samples loaded fatigue tests, microscopic and scanning electron microscopy analysis of welded joints of steel type IF (DC06EK) and DP (DP600MC) are done. The resulting values of endurance tests are graphically processed by the Wöhler curve.
