Abstract: 

In machine parts producing, the welding methods and the weldability of materials has an important role in determining the limit of utilization of any material and its successful application in some important areas. 100Cr6 steel is a high carbon steel which has a poor weldability by conventional fusion welding processes. However, Friction welding method can be chosen for joining this metal. In rotary friction welding, the joint is carried out in the solid state where the heat is generated by friction at the interface of the pieces during rotation under axial pressure. In order to evaluate the ability to weld this metal by friction, the main aim of the present work was to produce similar metal joints of this steel by rotary friction welding method and investigate experimentally the weld joint properties. The joints are produced from 100Cr6 steel rods having different diameter and different interface geometries. A microstructural characterization was carried out of friction welded specimens by optical microscopy. The Vickers hardness distribution at the weld joint was examined. The welds exhibit high hardness in the central zone, which was characterized by a martensitic structure.
