Welding Materials for Arc Additive Manufacturing

The emergence of heavy metal 3D printing technology meets the development needs of large and heavy metal components manufacturing, and has the characteristics of short process, green, and precise digital one-step molding. Additive manufacturing with arc as heat source is a special deposition welding process, which has extremely strict requirements on welding materials. The arc additive manufacturing supporting welding material developed by the iron anchor welding material has the characteristics of low S, P, high toughness, and the physical and chemical properties of the deposited metal are equivalent to or better than the forgings.
