The paper deals with analysis of welds-on quality of traverse crane wheels made from gr. 90–60 material, ASTM A148. Three types of welding-on technology with various filling materials were used. On wheel after wearing was welded-on one interlayer by a combination of additional materials, wire A 106 with F 11 addition and two cover layers made by a combination of A 508 wire with F 13 addition. Wheel surface was hardened after welding-on to a depth of 3 mm. A second welds-on technology was a combination of A 106 wire with F 11 addition. Two cover layers were made by a combination of RD 520 wire with F 56 addition. Third welds-on technology was realized to face one layer by C 113 wire in inert atmosphere: 80% Ar + 20% CO2. Two cover layers were made by wire with self protect Lincore 40-O. Properties of renovated traverse crane wheels were compared with the properties of new wheels with surface hardened layer. The welds-on were exposed to adhesive wearing where surface resistance was examined according to their weight loss. Influence of a particular element on the welds-on chemical composition was examined by EDX analyses.
