Özet
In this study, low carbon steel and copper plates were welded to each other by shielded metal arc and tungsten arc welding processes. Mechanical and microstructural properties of the joints were investigated. Tensile, bending and hardness tests of the welded specimens were conducted. Optical microscopy and SEM studies were carried out, in order to make the microstructural evaluation. During the tensile tests of the welded specimens, fracture occurred in the copper side apart from the weld region. Macro examination of the bended specimens showed no crack and tears. The results showed that hardnesses of the shielded metal arc welded specimens were higher than those of tungsten arc welded samples. However, hardness values of the weld metal were found to be lower than those of the low carbon steel but it was found to be higher than those of the copper side. From the results of metallographic examination, a uniform transition from parent metal to weld metal was observed in the weld region and more grain growth was observed in TIG welding specimens due to higher heat input when compared to the shielded metal arc welded samples.
