Laser shock peening (LSP) is a surface plasticity strengthening technique that enhances the mechanical properties of metallic materials by introducing residual compressive stresses and improving the microstructure on the material surface. The development of online monitoring technology can ensure stable and efficient production processes and further advance the technology in high-quality and high-efficiency production areas.
Laser shock peening (LSP) is a multidisciplinary surface plasticity strengthening technique that significantly enhances the mechanical properties of metallic materials by introducing residual compressive stresses and improving the microstructure on the material surface. The development of online monitoring technology for product quality in LSP can be used to ensure stable and efficient production processes on a large scale and can facilitate the further development of this technology in areas with high requirements for part quality and production efficiency. Although the scientific community has conducted extensive research on the online monitoring technology in LSP, there is a lack of comprehensive review of this technical scheme in the published relevant comments. This paper provides a comprehensive summary and review of the LSP quality online monitoring technology based on process physical signals, multi-source information fusion and advanced data-driven methods. This review also summarizes the basic principles of LSP and the technical metrics used to assess product quality and discusses the advantages and disadvantages of each sensing method and the challenges for its future development via comparative analysis. It is expected that this review will provide important theoretical guidance and technical solutions for the actual online monitoring of LSP.
