Increasing of the efficiency of electric arc overlaying process with control the hydrodynamics of the weld pool

The review of the situation in the field of modeling of penetration and surfacing areas of the weld meta was carried outl, research ways to control and stabilize the process of forming the weld pool and emerging with defects of formation. Developedwas dynamic model of the formation of the weld pool and associated defects in the weld seam. Based on these models, analyzed the relationship of the information signals ? the feed rate and speed of the jet?source as control system parameters of deposition process
