Abstract

The topic of this research is the investigation of technological processes of gas-powder laser cladding with the help of high-power diode lasers with rectangular cross-section of laser beam, the mutual influence of technological parameters of gas-powder streams and focused laser beam on the properties of clad layer (dimensions, shape, etc.) in particular. The research stages included the following:

  • Numerical simulation of gas-powder streams that exit nozzles with different configurations of the inner cavity;

  • Direct investigation of the influence of technological parameters on the dimensions of clad layer.

It was established that the use of multi-channel gas-powder delivery nozzles significantly influences the productivity and quality of laser processing.
