異種金属によるワイヤー＋アーク積層造形での溶融池温度と冷却固化過程の観察

Wire and arc additive manufacturing (WAAM) is one of the metal additive manufacturing methods. It can be used to deposit dissimilar metals. However, it is sometimes difficult to deposit dissimilar metals because their physical properties are different. So, we observed molten pool by using high-speed camera and measured the temperature field of molten pool with two-color thermography to investigate the effect of physical properties of each material on the temperature and size of molten pool.
