摘要：This work investigated the mechanical and metallurgical properties of medium carbon steel usingshielded metal arc welding process (SMAW) with reference to the weld metal, heat affected zone and parent metal.From the results, shielded metal arc welding (SMAW) of medium carbon steel increased the strength of the weldedjoint in particular the heat affected zone (HAZ), as revealed by lower impact strength, higher tensile strength andhardness values as compared with the parent and weld metal which is attributed to the fine ferrite matrix and finepearlite distribution as compared to the weld and parent metal. However, there was a loss of ductility at the weldedjoint resulting to brittleness of the material.
