The procedure of gas-metal arc welding (GMAW) has received much attention in recent years and has numerous beneficial applications in the industry, including car industry and ship building. It is expected that the GMAW parameters, such as arc voltage, welding current and welding speed, strongly affect the mechanical properties of welded joints. As one of the most important mechanical properties that should be taken into account by designers, we can mention the ductility of welded joint, which can be found as a result of bending tests. Thus, we perform the experimental investigation with an aim to determine the effect of the parameters of robotic GMAW on the ductility of welded joints in CK45 carbon steel. The accumulated results clearly illustrate that the ductility of welded joints is a monotonic function of the welding parameters.
