介绍了一种金刚石圆锯片的激光焊接系统 ,该系统采用半自动方式 ,由约束放电激励CO2 激光器、三工位光路转换器、焊接工作台及工装夹具组成。采用该系统进行金刚石锯片的激光焊接 ,研究了激光焊接工艺参数及其对焊缝弯曲强度、焊缝外观、金相组织及显微硬度分布的影响。
A laser welding system of diamond circular saw blade is introduced. The system uses semi - automatic mode, consisting of constrained discharge excitation CO2 laser, three - position optical path converter, welding table and fixture. The system was used for laser welding of diamond saw blades. The parameters of laser welding and its influence on the flexural strength, weld appearance, microstructure and microhardness distribution were studied.
