摘　　要：为更好地了解与掌握我国钛合金焊接技术发展现状与研究动向,使用专利检索与分析系统并结合网络学术平台检索“钛合金焊接”关键词,对钛合金焊接技术专利年度申请量变化、领域衍变趋势、申请人及区域进行了统计分析,同时对钛合金焊接保护装置,以及钛合金与不锈钢、铜及铜合金等异种材料焊接的重点专利进行了阐述。经统计表明,钛合金焊接技术专利年度申请量增加趋势明显,涉及的技术领域由最初的B部增加到A、B、C、E、F、G、H等多部。钛合金与异种材料的焊接技术已经成为研究热点,其与不锈钢、铜及铜合金焊接专利件数较多,技术相对成熟,但与其他材料的焊接专利申请量较少,尤其是与非金属材料的焊接。In order to understand and master the development status and research trend of titanium alloy welding technology in China,the keywords"titanium alloy welding"are searched in the patent retrieval and analysis system and online academic platform,a statistical analysis is made about the annual application quantity,field evolution trend,applicants and regions of the titanium alloy welding technology patents,and the key patents for titanium alloy welding protection device and the welding of titanium alloy and dissimilar materials such as stainless steel,copper and copper alloy are expound.The statistics show that the annual patent application quantity of titanium alloy welding technology increases obviously,and the technical fields involved increase from part B to parts A,B,C,E,F,G,H and so on.The welding technology of titanium alloy and dissimilar materials has become a research hotspot.There are many patents for welding of titanium alloy and stainless steel,copper and copper alloy,and the technology is relatively mature,but there is few patent applications for welding of titanium alloy and other materials,especially non-metallic materials.
