Study on Porosity Defect Detection in Narrow Gap Laser Welding Based on Spectral Diagnosis

As an advanced connection technology for large thick-walled components, narrow gap laser welding has the advantages of small heat input and high efficiency and quality. However, porosity defects are prone to occur inside the weld due to the complex welding environment. In this study, the influence o...
