In this study, 51CrV4 alloy steel bar was heated up to 900°C and rolled to produce round shape at the end of the steel bar. A gap takes place inevitably between the end and main part of steel. The gap should be closed by welding to avoid displace of bushing during the service life of tool. Therefore, rolled end part was welded to main body by gas-metal arc welding (GMAW-MIG) and the shielded metal arc welding (SMAW) methods. After filling the gaps, welded steels were annealed at 920°C for 50 minutes. In order to investigate the microstructure of welding regions, some samples were taken from welding areas. Present elements and chemical changing of the areas were analyzed by optical emission spectrometry. Sectional micro hardness was applied by Rockwell hardness unit. The residual stresses on the welded samples were investigated by X-ray stress analyzer based on solid state linear sensor technique.
