Mapping knowledge domain based visualization analysis on welding fume themed scientific reports

  • Objective To describe the hotspots and trends of worldwide research on welding fume.

    Methods Articles on welding fume published from 1941 to 2017 were retrieved from Web of Science TM core database. Cite Space (5.0.R1.SE.9.4) software was used to conduct co-citation analysis and burst analysis, and to obtain the distribution maps of countries, institutions, and authors, as well as the maps of high-frequency keywords, high-frequency burst terms, and references with strong citation burst.

    Results From 1941 to 2017, the top five countries publishing research articles on welding fume were the United States, Germany, England, Korea, and Sweden; the top two research institutions were NIOSH and Harvard University; the top one author was ANTONINI J M. The high-frequency keywords included exposure, welder, welding, manganese, inflammation, and disease. Through burst analysis, the research frontiers were divided into two phases:the first phase was study on the nosogenesis of lung injury and inflammation caused by welding fume, showing references with high-frequency burst based on case-control study and animal test and high-frequency burst terms as "arc welder" "Sprague Dawley rat" "risk" and "in vitro"; the second phase was the study of particulate matters, showing high-frequency burst term such as "ultrafine particle" "nanoparticle" and "aerosol".

    Conclusion Developed countries pay high attention to the studies of welding fume. The research on the pathogenic mechanism of welding fume has been mature, while the research of particulate matters is rising. China's research efforts in the field of welding fume are not sufficient, so more investments to the study field are required.
