Welding is a process of joining two similar or dissimilar materials together by application of heat. Welding processes are used with the aim of obtaining a welded joint with the desired weld-bead parameters, excellent mechanical properties with minimum distortion. The evaluation and discussion of effects of welding current on mechanical properties of welded joints for hot rolled low carbon steel plate and mild steel plate, having dimension of 60mm by 40mm by 8mm is investigated. The aim is to ascertain and compare the mechanical properties of the joints. The welded joints samples were cut machined and subjected to tensile test, impact toughness test, and hardness and their mechanical properties were determined. Generally, as the welding current increases, hardness of the weld increases for the two samples up to 115A and 116A for mild steel and low carbon steel respectively but shows a decrease with a further increase in welding current. The ultimate tensile strength decreases with increase in welding current but increases at the welding current of 200A and 115A for mild steel and low carbon steel respectively. The yield strength and impact strength shows a decrease for the two samples with an increase in the welding current.
