In this study, micro-alloyed steel samples were exposed to gas metal arc welding process by two welding wires coded ER100 SG and SG 3. Protection gases compositions were selected as 100% argon (Ar), 15% CO_2 + 85% argon (MIG/MAG-1) and 25% CO_2 + 75% argon (MIG/MAG-2) in three different types in order to investigate the CO_2 effect on mechanical properties. In addition, an electric arc welding electrode coded Fox EV 85 was selected for arc welding applications to research the effect of welding method in mechanical properties. Welded joint were prepared at 130 A, 20 V; 150 A, 22 V and 170 A, 24 V welding parameters. All welded joint specimens were exposed to tensile tests, Charpy impact tests to evaluate the yields strength, maximum tensile stress, fracture stress, % elongation values and ductile-to-brittle transition temperatures values. Micro and macrostructure photos and scanning electron microscopy micrographs of specimens were obtained. The optimum parameters were advised to users at the end of this study.
