| Abstract: | This paper deals with the calculating method for the effective heat utilization of laser during the broad-beam overlapping，the microstructure features of overlapping cladding layer and the convection mechanism，which was used to explain the variation of the microstructure and the distribution of alloys in different areas．The mechanical properties of the overlapping clad layer are measured． |
| Keywords: | overlapping effective heat utilization of laser convection mechanism mechanical properties |
