This study addresses to the laser cladding of nickel-based powders on stainless steel substrate. A TRUMPH pulsed laser and a coaxial cladding module are used to fabricate single tracks on AISI 304 substrate. The influence of the laser power on the geometric characteristics and microstructure of the cladded layer is investigated using optical and scanning electron microscopy and energy dispersive X-ray spectroscopy. Dilution is determined using the melt depth of the cladded tracks and validated using the local chemical microanalysis. The results showed that laser power have a major influence on the dilution and melted area of the laser cladded tracks.
