Abstract
Experimental data are given on the effect of composition of cladding consumables on formation of structure and mechanical properties of the deposited metal on wheels of steel 2. Strength properties, ductility and crack resistance of railway wheels repaired by cladding, were evaluated by analytical methods. It was found that to ensure the required combination of mechanical properties and high crack resistance of the base and deposited metals it is rational to apply cladding consumables of bainitic or bainitic-martensitic grade for repair of railway wheels of steel 2 by arc cladding.
