| 摘 要： | 对3003铝合金进行交流活性钨极氩弧焊(A-TlG)焊接实验,选用氧化物SiO2,TiO2和卤化物MnCl2,NaCl,CaF2作为活性剂,研究了单一成分表面活性剂对焊接熔深的影响。实验结果表明:涂敷活性剂可以一定程度的增加焊缝熔深;氧化物增加焊缝熔深的作用比卤化物大;TiO2作用最显著,熔深增加约80%,且焊缝无裂纹、气孔、夹渣等缺陷。

| Abstract: | AC A-TlG welding on 3003 Aluminum alloy is investigated.The single component of oxide SiO2,TiO2 and halide MnCl2,NaCl,CaF2 are served as activating fluxes to study the effect on weld penetration.The result shows that the A-TIG weld penetration with activating fluxes can be improved to a certain extent.The oxide has more effect to improve weld penetration than the halide.TiO2 has larger effect to improve penetration than any others,and penetration is improved about 80%,and there are no weld defects such as cracks,blowhole,and weld slag inclusions on weld joint. |
