In this study, the effects of welding parameters on the mechanical and microstructural properties of the weld zone and the TIG and MIG welds of low and medium carbon steels were investigated. Welding was carried out at constant welding currents and wire speeds and then tensile tests and hardness measurements were performed to determine the mechanical properties of welded joints. In addition, microstructure studies have been carried out to determine the changes in the microstructure. The aim of this research is primarily to examine how welding techniques affect material weldability and how the welded steels change in hardness, tensile test and microstructure characteristics in the heat affected zone (HAZ). Comparisons were made between the tests to determine the mechanical properties of certain metals and welded steels. Microstructures have also been used to assist in studying any porosity or other properties of the microstructure that may affect the performance of the welds under dynamic conditions.
