Summary:The procedure of gas-metal arc welding (GMAW) has received much attention in recent years and has numerous beneficial applications in the industry. The arc voltage, welding current and welding speed are three independent variables of this process that may affect the mechanical properties of the weld metal. As one of the most important mechanical properties of the weld metal, we can mention its yield strength and ultimate tensile strength. Therefore, we focus on the strength of the weld metal in CK45 carbon steel welded by the robotic GMAW process under different conditions. The accumulated results clearly illustrate that the strength of the weld metal is a monotonic function of the variables of welding.
