| 摘 要： | 采用卤化物（CaF2，ZnF2，MnCl2）、氧化物（SiO2，TiO2，V2O5）和单质Te作为表面活性剂进行钛合金A—TIG焊，研究了表面活性剂对焊接熔深的影响规律。结果表明：3种卤化物都能增加焊接熔深，其中MnCl2使得焊接熔深达到传统TIG焊的2倍以上：3种氧化物对焊缝成形几乎没有影响；Te能明显增加焊接熔深，减小焊缝熔宽。认为电弧收缩是卤化物但不是Te增加钛合金A—TIG焊熔深的主要机理。

| Abstract: | A-TIG welding for titanium alloy was carried out to study effect of surface activating flux on welding penetration. Halides(CaF2, ZnF2 and MnCl2), Oxides(SiO2, TiO2 and V2O5) and elemental Te were served as fluxes. It is found that the three kinds of experimental halides can improve welding penetration, especially the welding penetration for MnCl2 reaches two times of that of conventional TIG welding. The three kinds of oxides have little effect on weld forming. Elemental Te can curiously increase welding penetration and decrease weld width. It is believed, arc constriction is the main mechanism of halides improving welding penetration of A-TIG welding for titanium alloy, but not for elemental Te. |
