According to the different processes’ experiment results, observe the cross -section and its corresponding criterion of experimental results are reviewed also. The research results show, which whether using Fe and Nickel matrix FCW composites containing tungsten carbide particles, or aluminum, it can achieve very efficient results with extremely low heat input compared to other welding processes. However, depending on the material characteristics, such as iron-based FCW containing silicon carbide, according to the experimental results, iron and tungsten carbide will have a strong reaction at high temperatures in the hot-wire system, so that the welding process is unstable, resulting in unstable electrode shape, making this process unusable for this material. en_US DC.subject 雷射銲接 zh_TW DC.subject 堆銲 zh_TW DC.subject 半導體雷射 zh_TW DC.subject 熱絲 zh_TW DC.subject 積層製造 zh_TW DC.subject 複合銲線 zh_TW DC.subject Laser welding en_US DC.subject Cladding en_US DC.subject Diode laser en_US DC.subject Hot-wire en_US DC.subject AM en_US DC.subject Flux cored wire en_US DC.title Development of Overlaying Welding Method using Hot-wire Laser Welding Method en_US dc.language.iso en_US en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
