| Abstract: | The laser tailor welding craftwork was analyzed. The effects of laser power, welding speed and defocus on welding quality for high-power solid-state laser were studied, and the variation laws was plotted. The laser welding craftwork for common blanks of full thickness series in automotive industry was studdied, and the optimal welding craftwork for full automatic laser tailor welding line was obtained with the method of interative optimalization. |
