Investigation on the Process Characteristics of Laser Cladding Fabrication Using 45 Carbon Steel Wire

Abstract:

This study investigates the effect of wire feeding direction, angle, wire feeding speed, laser scanning speed and laser power in a high power Nd:YAG laser direct metal deposition process for single and multilayered clad/parts. The lap cladding experiment using 500 W Nd:YAG laser is designed to study the best lap rate of 45 carbon steel. The microstructure and micro hardness of the melting track shows that dense metal microstructure can be obtained using laser cladding.
