本研究採用TIG與MIG進行複合銲接，將TIG銲槍置於前端，透過MIG電弧熔融銲條與鋁合金板材接合。針對MIG進行不同保護氣體混合，包括Pure Argon、ArHe、ArCo2，探討保護氣體對於鋁合金複合銲接特性之影響，同時探討銲後熱處理對銲件微觀組織與微硬度之影響。實驗結果顯示添加Co2時得到較深的熔深，而銲道表面較不美觀且出現較多飛濺物；添加He時得到高熔深、高熔填效率且較美觀的銲道。銲道微觀組織由SEM及OM分析，觀察出添加不同保護氣體時，銲道形貌與微觀組織相較於熱影響區與熔融區無顯著變化；X光繞射分析顯示，未熱處理之銲件微觀組織由α-Al、Al(Mn, Fe)Si及Mg2Si和Si幾種不同相組成。當銲件經過人工時效後，Al(Mn, Fe)Si轉變為細長針狀組織，Mg2Si穩定相析出且均勻分布於鋁基地，使銲件硬度得到顯著提升。總和實驗結果得到結論，使用高比例之ArHe混合氣體作為保護氣體為最佳選擇，能夠降低銲接時產生氣孔的風險以及減少表面飛濺物，得到較高的銲接品質與銲接效率。.

520 3 $a The objective of this study was to find out the influence of the composition of shielding gas on the weld properties in the tungsten inert gas and inert gas (TIG-MIG) hybrid welding process of aluminum alloy plates. TIG welding was used in the leading position, and MIG welding in the trailing position produced metal droplets by melting the welding wire. Hybrid welding experiments were performed to obtain bead-on-plate weld deposits at various shielding gas mixtures for MIG welding include argon/helium and argon/carbon dioxide, and different post-weld heat treatments were carried out after welding. The results showed that increasing the content of carbon dioxide in the shielding gas, although leading to excessive spatter generation and uneven bead appearance, provided deeper penetration. The addition of helium to the shielding gas improved the bead appearance and provided better penetration and high deposition rate. The microstructures of the welds were examined by scanning electron microscope and optical microscope. When the shielding gas composition changed, the phase morphology or microstructure did not change significantly, except for the expansion of fusion zone and heat-affected zone regions. X-ray diffraction test indicated that the as-weld microstructure consisted of α-Al plus several morphologically distinct phases of Al(Mn, Fe)Si, Al2FeSi, Mg2Si and Si phase. After artificial aging, the Mg2Si phase was homogeneously distributed throughout the aluminum matrix in fine grain size, while the Al(Mn, Fe)Si phase was formed long and needle-type. The Mg2Si precipitates were the final stable phase and therefore greatly improved the hardness of weld metal. Finally, a higher percentage of helium in the shielding gas could be a better option, since fine bead appearance, reduced the risk of weld porosity and less spatter formation would result..
