用一种新型焊丝焊接TC18钛合金的接头性能与组织研究

Investigation on Mechanical Properties and Microstructure of TC18 Titanium Alloy Welded Joints Made by New Developed Wire

对采用研制的焊丝和采用TC18同质焊材钨极氩弧焊焊接TC18钛合金的接头力学性能及微观组织进行了对比研究,结果表明:采用同质焊材焊接TC18钛合金只能保证接头的强度指标,而采用研制的新型焊丝焊接TC18钛合金,可以保证接头具有优良的综合力学性能。

The feasibility of using a new developed wire to weld TC18 titanium alloy was discussed.The mechanical properties and microstructure of the joints joined by the new developed filler metal and TC18 filler metal were compared,the results showed that only the strength of the joint joined by TC18 filler metal was satisfied,while the comprehensive mechanical properties of the joint joined by the developed filler wire were ideal.
