Sažetak

High automation, high speed and high efficiency are the advantages of laser welding metallurgical products. It is a great significance to study the quality of laser welding. In the paper, the input current and pulse width of laser are used as variables to improve the tensile strength of welding samples. Firstly, the effect of current and pulse width on tensile strength is obtained through experiments. Then the fitting formula and cureve of experimental data are obtained by orthogonal regression method. Finally, the prediction and optimization of tensile strength are carried out, and the error of the results is less than 12,5 %, indicating that they have a certain guiding role.
