内容記述 | Author have described the surface-cooling laser welding method to avoid the thermal damage generated on the surface by irradiation of laser for welding of thermoplastics in the first report. There is a problem of bubbling within a laser-welded plastic substrate due to concentration of heat generation by irradiating a Gaussian distribution laser beam. For more detailed confirmation of the effect of laser beam intensity distribution on temperature distribution within a processed workpiece, comparison of the difference in the effects of “top-hat-beam laser” by homogenizing the distribution of laser intensity and Gaussian distribution laser beam was investigated by numerical analysis in this study. In the case of irradiation of Gaussian beam, the heat generated inside plastic sheets due to the beam intensity distribution, causing the temperature at the center to become extremely high, and conversely, the temperature at the outer edge is kept low. On the other hand, in the case of irradiation of top-hat beam, nearly uniform temperature distribution in the radial direction at the interface compare to in the case of Gaussian beam. the temperature difference within the beam radius becomes so large that the weld width that guarantees the actual weld strength is also narrowed. It was confirmed that the welding width is narrow in the case of Gaussian beam and wide in the case of top-hat beam. | |||||
