The selection of the welding process is a significant step before fabricating welding structure. The integrity of the weld joint depends on the selection of the welding process, welding parameters along with thermal distribution across the welded section. The present study is to investigate the mechanical and microstructure in low carbon steel IS2062 grade E550 BR joints made using SMAW (shielded metal arc welding) technique. The formation of bainite and ferrite in the joint make it more brittle whereas mechanical properties increase significantly like toughness and hardness.
