Abstract

Precision Nd:YAG laser cladding was investigated to achieve laser clads with specific pattern and roughness on very thin metal sheets (0.1 - 0.15 mm) to meet industrial requirements. Characterization of pulsed laser cladding on thin sheet substrate, side nozzle, coaxial nozzle and development, high speed video visualization of powder flow for both nozzles, microstructure evolution, vacuum clamping, chiller cooling were presented. Sound laser clad pattern with height/width ration 0.88 or 0.50 and identical quality was obtained. The present work demonstrates that precision laser cladding and/or direct laser manufacturing on thin sheet is another attracting field on laser cladding.
