AB  - Purpose– The aim of the research is to investigate the influence of gas metal arc welding on the wear performance of worn concussor jaws.Design/methodology/approach– Worn parts were welded using the gas metal arc welding process. Various wires were used for this purpose. These welded parts were subjected to wear tests under different loads, and changes in the hardness and microstructures were examined. A pin‐on‐disc wear test apparatus was used.Findings– As a result of this study, the following findings are reported: wear rates were significantly increased with the increasing of load and wear distance; the hardness of the weld metal of the welded specimens changed depending upon the chemical composition of the weld wire; with the increasing carbon, manganese and chromium in the weld wire, wear resistance increased; in the present study, specimens B and C showed better wear resistance; therefore these specimens are suitable for using in concussor jaws.Research limitations/implications– Electrodes were limited with four wires, for welding gas arc welding methods were applied, loads were limited with 10, 25, 40 N, welded parts were subjected to wear test, hardness test, microstructures were examined.Practical implications– For future work, instead of buying worn concussor jaws, they are repaired with the gas metal arc welding process using various weld wires. By this process, working life of the jaws can be extended and vast economical benefit may also be obtained.Originality/value– This paper fulfils an identified information need and offers practical help to the industrial firms working with alunit ore and rock crasher and also to the academicians working on wear of materials.
