Absorption Characteristics of Amorphous Metal during Processing with Nd:YAG laser

Nd:YAG 레이저를 이용한 비결정질 재료의 용접 시 레이저의 흡수 거동

For the conventional welding method. the high heat transfer makes the crystallized zone of the work material unavoidable. Whereas the laser is able to weld the amorphous metal without a crystallized zone, because heat transfer is limited within a very small restricted volume. In this paper, the possibilities and the limits of the laser welding were studied to utilize the advantageous properties of amorphous metal foils.
