The article presents the effect of burnishing on the surface roughness and hardness of the EN AW-6060 aluminum alloy after welding. The samples prepared were welded using the 141-TIG method, and then the surfaces to be burnished were prepared in the turning process to remove the weld face and run-out of the workpiece. After the turning process, the process of surface plastic treatment by roller burnishing began. Then, measurements of surface hardness and selected surface roughness parameters were performed. The analysis of the test results showed an increase in the hardness of the surface layer and an improvement in the surface roughness parameters Ra and Rt.
