This paper presents an experimental research on the metal parts manufactured by laser cladding. The present studies showed two processes were conducted ,including coaxial powder-feed cladding and pre-placed powder cladding. The effect of processing parameters were studied and optimum set of parameters for the superior surface quality was established by employing the orthog -onal design. The manufactured parts were subjected to metallographic examination and micro -hardness measurement. Results showed that the microstructure of coaxial cladding parts was better than that of pre-placed powder cladding parts. The micro-hardness of the manufactured specimen along and vertical the scanning direction were measured using a HVS-1000 micro-hardness tester with a 200g applied load. Analysis of the physical properties provided further evidence of differences in micro-hardness produced by different process conditions, and the average micro -hardness value of pre-placed power cladding layer was lower than that of the coaxial powder-feed cladding layer.
