Research Status and Trends in Welding Process Quality Monitoring Technology

In order to comprehensively explore the overall status and development trend of welding process quality monitoring technology research, 995 welding quality monitoring papers from 1979-2024 based on Science Citation Index (SCI) and Social Sciences Citation Index (SSCI) were analyzed using the CiteSpace and SciExplorer software. Cite Space and SciExplorer software was used to carry out data statistics and knowledge mapping analysis. The results show that the papers on welding quality monitoring mainly focus on laser welding, aluminum alloy materials and neural networks; the output of the papers mainly focuses on the formation of different research teams with Shanghai Jiaotong University, Guangdong University of Technology, University of Michigan, and Huazhong University of Science and Technology as the core; and the development of research on welding quality monitoring during 1979-2024 is divided into four phases, namely, preliminary exploration, slow accumulation, rapid development and deepening expansion.
