Abstract: Conventionally, the metal joining process used to be carried out using fasteners and rivets. Since, the advancements in technology, the metal joining process is now performed via welding. Because welding affects the mechanical properties, the importance of welding parameters to determine mechanical properties of welded plates is in consideration. This research reviews the impact of Shielded Metal Arc Welding (SMAW) parameters on mechanical properties of low-carbon, mild and stainless-steel welded joints. It is necessary to understand the welding parameters to get the product of desired quality. In the past studies, the welding parameters: welding speed and current, were taken into consideration to find the impact via Destructive Testing (DT) which includes hardness and tensile tests. The present study aims to review the impact of welding parameters on hardness and tensile tests carried out in past.
