摘　　要：通过采集激光焊接过程的光谱信息,根据波长强度图分析不同光谱区内元素含量及其辐射强度,该文研究了不同元素在不同的光谱区内对激光焊接质量的表征,分析了光谱信息与焊接质量的关系,为根据元素在不同光谱区种类和含量的变化判断焊接质量提供依据。According to the spectral information collected by spectrometer during laser welding process, the element content of and radiation intensity in different spectral regions are analyzed based on the wavelength intensity drawing. In this paper, the characterization of laser welding quality of different elements in different spectral regions is studied and relationship between spectral information and welding quality is analyzed, and then, for changes in type and content of applied elements in different spectral re-gions reflecting the welding quality, a reference basis is provided.
