Multiple Quality Characteristics Optimization of Welding Aluminum Foam

[[abstract]]隨著科技的迅速發展、產品輕薄短小趨勢的來臨，輕量化材料與具環保回收性材料已成為當今研發設計與開發的主軸。近年來，一種具有輕量化特性的材料-發泡鋁，由於又同時具有高比強度、高比剛性，電磁波吸收性，耐衝擊性，耐燃等特色，使其在工業應用上非常廣泛。近年來，應用於運輸工具之結構件及吸收衝擊能零件方面之潛力也頗大。 本研究是利用各種銲接參數的組合方式，接著再應用田口主成份分析法、田口主成份結合模糊理論分析法，針對平板發泡鋁銲接後的彎曲強度以及銲道微硬度等品質特性，分別推論出MIG電弧銲接平板發泡鋁以及CO2雷射搭配MIG電弧混合銲接平板發泡鋁多重品質最佳化的銲接參數組合，使各品質皆能獲得顯著改善。[[abstract]]With the progress of technology, aluminum has a wide variety of alloys, such as aluminum foam. Due to its excellent properties, it has attracted significant attention. It also considered to be a class of promising future development of engineering materials, in the automobile, transport, construction, electronics and aviation industry and other areas with wide application. In the experiment , various welding parameter combinations were considered to explore the bending strength and bead micro-hardness. Taguchi-PCA, Fuzzy-based Taguchi-PCA were utilized to derive the multiple quality characteristics optimum parameter combination for MIG arc welding and hybrid welding for aluminum foam in order to enhance various properties significantly
