| 摘 要： | 激光中心温度探测是激光领域的一个重要课题，直接影响着激光在工程技术中的应用。利用XL-800WF光纤传输多功能脉冲激光加工系统，照射厚钢板，得到钢板的熔化图。通过显微镜测量熔斑的直径，从而计算液态钢的凝固时间。根据激光温度的扩散原理，建立理想条件下钢板的热传导方程，模拟出钢板的温度演化规律。结合凝固时间，推导了XL-800WF光纤传输多功能脉冲激光中心温度的理论值。

| Abstract: | The temperature detection of laser is an important subject in the field of laser, which affects its applications in engineering directly. The XL-800WF multi-function laser welding machine was used to irradiate the thick steel plate and the melting graphs were recorded. From the micrographs, we can measure the melting spot size and calculate the solidification time. According to the principle of the spread of laser irradiation temperature, we have built the heat conduction equation under ideal conditions and simulated the temperature evolution. Combining with the solidification time, we have derived the theoretical temperature value of XL-800WF laser. |
