一些铝 6061 合金与 Al-Si filler 电线用绕过当前的双 sided 弧焊被焊接在微观结构, microhardness 和焊接关节的腐蚀行为上调查 Al-Si 金属间化合的混合物的效果。试验性的结果显示艾尔 4.5 在焊接关节的干舷的 FeSi 阶段在背后比那好并且最新形成了艾尔 0.5 Fe 3 Si 0.5 在背后被观察。在焊接增强 Al-Fe-Si 的阶段的形成在大约 18% 改进了焊接的 microhardness。当腐蚀水流显示了反面时,焊接地区的腐蚀电阻比贱金属的大,并且焊接区域的腐蚀电阻比贱金属的好。
Sheets of aluminum 6061 alloy were welded using bypass-current double-sided arc welding with Al-Si filler wire to investigate the effect of Al-Si intermetallic compounds on the microstructure, microhardness and corrosion behavior of weld joint. Experimental results indicated that the Al4.5FeSi phase in the topside of the weld joint was finer than that in the backside and newly formed phase of Al0.5Fe3Si0.5 was observed in the backside. The formation of reinforcing phases of Al-Fe-Si in the weld improved the microhardness of the weld by about 18%. The corrosion resistance of the weld zone was greater than that of the base metal, while the corrosion current displayed opposite, and the corrosion resistance of the weld region was better than that of the base metal.
