Additive Manufacturing Based on Welding Arc: A low-Cost Method

The objective of this paper is to present a review of a new developing manufacturing technology based on welding of metallic materials. Additive manufacturing (AM) is based on robot welding and it has showed the high flexibility, efficiency, fast output, good quality and low cost. This paper explores several common welding materials and manufacturing technologies include the shield gas, materials engineering, processes and most concerned commercial interests. AM has the potential to revolutionize the global parts manufacturing and industrial tendencies with the rapid development of increasing material manufacturing technology. AM based on arc welding has the big advantages of high efficiency and low cost, which makes it possible to use in many industries although it has a little bit poor surface qualities compare to AM based on laser and electron beam manufacturing.
