The most perspective welding technology of additive manufacturing of three-dimensional objects is plasma-arc technology with application of wires or powders. It allows creating at comparatively low heat input quality volumetric products with wall thickness from 3 to 50 mm from alloys based on Fe, Ni, Co, Cu, Ti, Al, as well as composite materials, containing refractory components.

During the experiments established that the proposed purification technology is 5 or more times faster separation of waste into liquid and solid fractions, and also enhances the quality of treated water as compared with conventional multi-stage cleaning.
