摘要
以1mm厚的铝板为实验研究对象,采用脉冲激光进行铝壳立焊焊接实验,对焊接速度、脉冲能量进行优化。通过对焊接试样抗拉强度测试、焊缝的形貌和显微硬度的分析,焊缝热影响区较小,焊缝区的强度、硬度和母材接近。
In this paper,the 1mm thick aluminum plate as the experimental research object,using the pulse laser to carry out the welding experiment of the aluminum shell,optimize the welding speed and pulse energy. Through the analysis of tensile strength test,weld appearance and micro hardness,the heat affected zone is small,the strength and hardness of the weld zone is close to that of the base metal.
