The effect of welding current on the tensile properties of low carbon steel welded joint was investigated in this research. In this work mild steel plates were joined by shielded metal arc welding process which is also known as manual metal arc welding used to examine optimum welding current. The welded samples were cut and machined to standard configurations for tensile tests. It was concluded that variation of current affect the tensile properties of the low carbon steel welded joint. As the current increases from 80A to 110A, the ultimate tensile strengths and yeild strength increases. The percentage elongation decreases with increase in welding current but increases at the welding current of 110A.
