Claim:
1. A wear-resistant roller for crushing of particulate material, for use in the cement or minerals industry comprising: a roller body, a wear surface on the roller body, the wear surface comprising welding beads comprising a primary fraction of carbide material and a secondary fraction of material selected from the group consisting of nickel, nickel alloys, mixtures of nickel and nickel alloys and mixtures of nickel containing refractory hard materials, cobalt, cobalt alloys, mixtures of cobalt and cobalt alloys and mixtures of cobalt containing refractory hard materials, the welding beads being welded to the roller body in an overlapping manner such that two neighbouring welding beads comprise an overlapping volume and a non-overlapping volume, and the overlapping volume having a higher wear resistance compared to the non-overlapping volume having a lower wear-resistance.
