	%X In the present investigation, H13 tool steel has been
deposited on copper alloy substrate using both CO2 and diode laser.
A detailed parametric analysis has been carried out in order to find
out optimum processing zone for coating defect free H13 tool steel
on copper alloy substrate. Followed by parametric optimization, the
microstructure and microhardness of the deposited clads have been
evaluated. SEM micrographs revealed dendritic microstructure in
both clads. However, the microhardness of CO2 laser deposited clad
was much higher compared to diode laser deposited clad.
