| 摘 要： | 以4种金属单质镉、锌、钛和铬作为镁合金A-TIG焊的活性剂,分析了不同金属单质对焊缝形貌、电弧形态及电弧电压的影响.结果表明,与常规TIG焊相比,镉和锌活性剂均增加焊接熔深,钛活性剂对焊接熔深不起作用,铬活性剂反而减少焊接熔深;涂敷镉和锌时,焊接过程中电弧形态收缩,电弧电压增加;涂敷钛和铬对电弧形态和电弧电压基本没有影...

| Abstract: | Four kinds of metal cadmium,znic,titanium and chromium were used as the activating fluxes for the A-TIG welding of magnesium alloy and the influence of metal activating fluxes on the weld morphology,the arc shape and the arc voltage has been analyzed.The results indicated that compared with the conventional TIG welding,both znic flux and cadmium flux increased the weld penetration depth,while the chromium flux redcued it and the effect of Ti flux was negligible.It could also be observed that the arc concent... |
