摘　　要：通过分析光学元件激光束和频率,提出优化激光焊接过程反馈控制的方法。根据实验结果,讨论激光光束焦距和其他特性之间的相关性,焊缝熔深和频率特征及其形成方法。该方法效率较高,通常用于模拟工业实际生产,并有助于设置各种焊接参数。This paper presents a novel method for optimization and feedback control of laser welding process.It is based on frequency analysis of the light emitted during the process and adaptive shaping of the laser beam achieved by an active optical element.Experimentally observed correlations between the focal properties of the laser beam,the weld depth and the frequency characteristics of the light emissions,which form the basis of the method,are discussed in detail.The functionality and the high efficiency of the method are demonstrated for a variety of welding parameters settings usually used to simulate industrial practice.
