Abstract

The paper presents problems related to the regeneration of wheel hubs for mining machinery vehicles carried out with arc welding using the MAG method. Hubs made of medium-carbon cast steel, type LII500, were weld surfaced with filler metal grade of G4Si. The tests were aimed at determining welding imperfections and metallographic properties of the surfacing welds. The influence of heat treatment on the properties of surfacing was investigated. Hardness distributions in welded hubs after various heat treatment operations were determined. Recommendations for the technology of weld surfacing the wheel hubs were formulated.
