Welding technologies are the fundamental application in industrial field especially for engineering, manufacturing and even medical implants. It involved consolidation of materials through adhesive and cohesive forces between metals with the present of thermal (heat) energy and pressure. Since the process involved in form of heat energy, adequate control of welding parameters is essential during welding process as it determined the quality of welded joint. In this thesis, the objective is to investigate the effect of SMAW process parameters on metallographic studies and mechanical properties of low carbon joints, with the aim of enhancing the quality and mechanical performance of the welded joints throghout series of well controlled welding parameters.
