钛合金熔化焊技术研究现状及发展趋势
Research Status and Development Trends of Titanium Alloy Melting Welding Technology
摘要
Abstract
Focusing on the fusion welding technology of titanium alloys,this paper systematically reviews the research prog-ress of mainstream processes such as laser welding,gas shielded welding(TIG/MIG),and laser-arc hybrid welding:it re-veals the formation mechanisms of joint brittleness,porosity,and cracks in different welding methods,and clarifies the con-trol rules of process parameters(such as laser power,shielding gas flow rate)on the microstructure(α'/β phase evolution)and mechanical properties of the weld;it particularly analyzes the breakthroughs of new processes,including the deep melt-ing mechanism of keyhole TIG welding,the melting depth enhancement effect of vacuum laser welding,the composition op-timization strategy of laser filler welding,and the adaptability of laser-arc hybrid welding to dissimilar material connections.In view of the current challenges such as the difficulty in controlling defects in thick plate welding and the formation of brittle phases at the interface of dissimilar materials,it is proposed that future breakthroughs are needed in intelligent defect monitoring,the development of special cored wires,and multi-energy field collaborative welding,providing theoretical and technical support for the efficient and high-quality connection of titanium alloy components.关键词
