【Abstract】 The laser cladding process is analyzed and the key parameters affecting the cladding quality are selected. Based on the above processing parameters, the experimental flow and analysis method of multi-pass laser cladding process test for practical teaching of mechanical and material majors in colleges and universities are designed in detail. The hardware structure of laser cladding process test platform and the selection of laser cladding materials are introduced. The actual teaching results show that the design of the program is reasonable and suitable for practical teaching in colleges and universities.更多还原
