Automatic arc welding and overlaying welding of steel using waste materials powder
AbstractSteel P6M5 and cast iron chips, TiO2, TiC, Fe-70% Mn and Fe-60% Cr powder mixtures were spread over the Cт3 steel surface and melted by continuously sup-plied welding wire’s Cв08 arc. Tensile strengths of the Cт3 steel weld produced using glass and glass and cast iron powder mixture was not less than that of Cт3 steel welded by Cв08 wire under standard flux AMS1. Resistant to abrasive wear layers ware obtained in overlaying welding of the Cт3 steel with waste materials powder. Selecting composition of powder mixture spread over the Cт3 steel surface and melting the powder with Cв08 wire arc enables to produce the layers more resistant to abrasive wear than those of hardened tool steels.
