Abstract
Peculiarities of fracture of welded joints between austenitic steel 10Kh13G18D and pearlitic steel 09G2S under vibration loads were investigated. The investigation results allowed identification of the mechanism of impact by technological factors in welding on service crack resistance of the above joints.
Keywords: arc welding, dissimilar joints, cracks, vibration loads, structural and mechanical inhomogeneity, fusion zone, -phase precipitation, deformation ageing, welding technology
