This paper discussed the effect of welding variables on the heat-affected zone (HAZ) by using a tensile test of welded 10 mm thick low carbon steel AISI1010 commercial plate, which is welded using the Shielded Metal Arc Welding (SMAW) method. Different welding electrodes E6013 and E7018 were considered as welding parameters investigated. After that, the welded specimens were cut and machined to standard configurations for tensile test. The results showed that selecting different welding electrodes had a remarkable effect on the mechanical properties such as the ultimate tensile strength, elongation percentage, and yield strength of the welded specimens. The increment in the electrical current for each electrode in the welding processes led to decrease in yield strength and tensile strength. The initial decrease in tensile strength and yield strengths were observed. This behavior was attributed to the fact that different welding electrodes and increased the required electrical current to melting for the welding electrode, increased the electrical current led to increased heat input on heat affected zone (HAZ), then the observed change mechanical properties [which could create area for defect. The welding processes and tensile test at a room temperature was performed
