Investigation and Modeling of the Process of Formation of the Pad Weld and its Microstructure during Laser Cladding by Radiation of High Power Fiber Laser

Abstract

The article gives theoretical solution of the problem of powder particles heating and their transfer to the substrate, considering the impact of transporting gas jet incidence on the substrate. The article also describes the research of layer microstructure, deposited by high power fiber laser cladding, and result of analysis of the dependence metal properties from the transition-layer cladding mode.
