摘　　要：基于国家知识产权局(SIPO)专利检索数据库以及Webpat全球专利数据库等分析工具,以铝合金焊接先进技术为研究对象,从国际角度、国家层面、专利权人与发明人层面进行全球专利数据的检索和分析。分析显示,美国、日本和欧盟国家铝合金焊接技术处于世界领先水平,中国近些年发展迅速,但核心技术较少;技术领先跨国企业重视对全球市场的专利保护,中国企业的专利保护区域较为局限。因此,对铝合金焊接技术的竞争形势进行了分析,为中国政府、企业制定产业战略提供参考。Based on the patent retrieval database of State Intellectual Property Office（ SIPO） and the Webpat global patent database,global patent data are retrieved and analyzed for advanced welding technology of aluminum alloys,from the perspectives of the world,the state,the patentee and the inventor. The result shows that while Europe,the United States,and Japan are on a worldwide leading level in aluminum welding,China has been developing rapidly in recent years but owns tiny central technology. Multinational enterprises which are equipped with leading technologies attach great importance to the protection of patents on global markets,nevertheless,Chinese enterprises＇ patent protection area are relatively limited.Therefore,competition situation of aluminum alloy welding technology is analyzed to provide the analysis result as references for industrial strategies of Chinese government and enterprises.
