Progress of global welding research progress based on big data（2014～2018）

基于大数据的全球焊接研究进展（2014～2018年） Progress of global welding research progress based on big data（2014～2018） 李洋 LI Yang 1 first-author 罗震 LUO Zhen 1 郑博方 ZHENG Bofang 1 王帅 WANG Shuai 1 罗丹青 LUO Danqing 2 金帅 JIN Shuai 2 天津大学材料科学与工程学院 天津大学材料科学与工程学院 School of Materials Science and Engineering,Tianjin University School of Materials Science and Engineering,Tianjin University 中国机械工程学会 中国机械工程学会 Chinese Mechanical Engineering Society Chinese Mechanical Engineering Society 以2014～2018年Web of Science (WOS)数据库和中国知网(CNKI)数据库收录的焊接领域学术论文、德温特创新索引(DII)数据库和CNKI专利数据库收录的焊接领域发明专利以及中国国家自然科学基金委批准的焊接领域基金项目为研究对象,利用可视化技术绘制出全球焊接领域研究机构、研究人员、研究热点等的科学知识图谱。指出我国机构和学者对全球焊接领域论文、专利贡献最大。"接头—微观结构—力学性能"是全球焊接领域的研究主线。与日本、美国等焊接制造强国相比,我国焊接技术在产学研转化及企业创新方面尚有不足。 In this research,big data and visualization technologies were used to establishthe knowledge maps of research institutions,researchers,and research hotspots in the global welding field based on the papers indexed by the Web of Science（Wo S） database and the CNKI database,patents indexed by the Derwent Innovation Index（DII） database and the CNKI China Patent database,and projects funded by the National Natural Science Foundation of China from 2014 ～2018. The findings of this study pointed out that research institutions and scholars from China have contributed the most to the papers and patentsin global welding field. "Joint-microstructure-mechanical properties" is the main line of research in the global welding field. The study also found that compared with Japan,the United States and other welding manufacturing power countries,China is still weak in the transfer and transformation of science and technology achievements,and also the innovation ability of Chinese enterprises. 焊接 大数据 知识图谱 发展现状 研究热点 welding big data knowledge map research progress research hotspot {G353};TG40 天津市自然科学基金(19JCZDJC39000);国家重点研发计划(2018YF1107904) 2022-03-08 1 51
