| Abstract Welding process is one of the joining methods of metals. It can be applied in the solid and fusion states. In the fusion state welding, the amount of the heat generated highly affects the quality of weldments from the mechanical properties point of view. To study this effect, three different fusion welding techniques were used to weld low carbon steel samples: Shield Metal Arc Welding (SMAW), Metal Inert Gas Welding (MIG), and Oxy Acetylene Welding (OAW). These weldments were subjected to different types of loadings to investigate their ability to withstand these loading conditions. The results showed that MIG weldments have the best mechanical properties among the other welding techniques if compared with the properties of the base metal. Keywords: SMAW, OAW, MIG welding, mechanical properties, low carbon steel. Introduction: Plenty of engineering applications adopt plain carbon steels as engineering materials for designing different parts of these applications. Plain carbon steel is an alloy consists of iron as the main metal and carbon percent not exceeding 1.5 % by weight, and some other elements such as manganese, copper, silicon. | ||
