本研究係針對1100及6061 (T6) 二種鋁合金板材實施噴炬式硬銲，採用目前工業界對鋁合金硬銲最普遍使用之BAlSi-4及TA100二種填充金屬為填料，在搭接之接合方式下分別探討二種鋁合金應用二種填料硬銲之最佳銲接參數，並透過拉伸試驗比較二種填充金屬銲接後之強度，且透過微硬度分析及金相觀察以瞭解材料硬銲後組織之變化情形。
實驗結果顯示1100鋁合金以BalSi-4及TA100二種填充金屬在最佳之硬銲參數下銲接後，其強度相近；6061 (T6)鋁合金則以TA100填充金屬硬銲後之強度較優。在最佳之硬銲參數下，二種鋁合金之臨界搭接距離均較理論值3T丁來得小。
1100鋁合金及6061 (T6) 鋁合金在硬銲後母材之強度與硬度均會下降。1100係屬於加工硬化型之合金，硬銲後無法再施以冷加工硬化，需要加以注意。而6061 (T6) 鋁合金屬於析出硬化型合金，銲接後建議可再實施熱處理以恢復其機械性質。
1100鋁合金銲接後，在銲道邊緣會有矽之擴散作用而使硬度提昇，6061 (T6) 鋁合金則不會產生此現象。

In order to explore the best brazing parameter, torch brazing is used to braze the wrough aluminum alloy plates of 1 100 and 6061(T6) by using filler metals of BAlSi-4 and TA1OO in the type of lap joint. The joint shear strength was compared through the tensile test. Further more, the change of microstructure was examined by optical microscope and micro hardness test.
The result showed that there is no different between the joint shear strength using the filler metals BAlSi-4 and TA1OO for 1100 aluminum alloy. For the wrough 6061 (T6) aluminum alloy plates, the joint shear strength of brazing filler metal TA 100 is higher than filler metal BAlSi-4.
There are reduction in the strength and hardness of base metal for bath 1100 or 6061 (T6) wrough aluminum alloy plates. Because the wrough 1100 aluminum alloy plate is strengthened by cold working, brazing heat caused recrystallization and increase in grain size. The decrease of mechanical properies of wrough 6061 (T6) aluminum alloy plate was obtained by heat treatment during brazing.
In addition, there is diffusion of Silicon in the weidment of wrough 1100 aluminum alloy plates and promote the increase of hardness of base metal. But no diffusion was observed in 6061 (T6) aluminum alloy.
