摘要

本文对Innography专利数据库收录的1997-2016年世界范围内申请的激光焊接技术专利进行了数据计量分析,分析了全球激光焊接技术专利的年度分布、地区分布、研发重点分布、机构分布等,揭示了已展现出明显优势的激光焊接技术的创新现状和发展趋势,所得到的结果可为这种新技术的研发决策提供支持与依据。研究发现,激光焊接技术近年来发展迅速,美国和中国在激光焊接技术研究领域占据主导地位,且研究资助力度持续增加。
        The paper metrologically analyzes the data of the laser welding technology patents(1997-2016) collected worldwide by the Innography database,and investigates the variation of the annual patent amount in the period,the patent amount of each major country,the key techniques of the patents,and the patent amount of each major enterprise,and finally,elaborates the innovation status and development trends of the laser welding technology,the performance superiority of which is obviously emerging. The results of the study can provide the support and basis for decision on the new technology research. After analysis,the author finds out that laser welding technology develops swiftly in recent years,the United States and China dominate the field of laser welding technology research,and their research fundings continue to increase.
