Paper Abstract

Unsteady heat transfer with simultaneous melting and crystallization at laser cladding process with coaxial metal powder injection is investigated numerically. Numerical modeling determined that the main parameters that govern melt pool dynamics and system maximum temperature are mass feed rate, laser power and scanning speed. Also it is determined that taking in to account the kinetics of phase change results in melt pool boundary and melting temperature mismatch. Dimensions of melted zone and cladding height are compared with experimental data.
