Abstract
Laser technology process is a pulsating practice to the field of engineering and in all paces
of lifespan; since it can travel a longer distance and be focused to a very small bright spot
that exceeds the illumination of the sun. This present study reports the modeling and the
prediction of the volume of laser deposited composites using the central composite design
(CCD). Four input factors were put into consideration which is the laser power, the scanning
speed, the powder flow rate and the gas flow rate. Titanium alloy (Ti6Al4V) and copper (Cu)
have been coaxially deposited to form a bulk of single clad. The factors considered determine
the energy density and the melt pool delivered into the substrate and as such, influenced the
volume of the deposited composite (VDC) which was employed in the response surface
methodology (RSM) design. This has been used to predict the actual process parameters for
the optimum process setting.
