Abstract
The technique of ultrasonic welding has been successfully applied to amorphous alloys, which can be welded to some amorphous alloys and to other metallic materials such as aluminium and copper etc. Those welding techniques can be considered for possible application where the welding is achieved either at a low temperature or by a short welding time of a thin surface layer followed by ultrasonic welding. The short time heating at the interfaces during the welding process has no effect on the crystallization of amorphous alloy. The weldability of such a materials must be strongly limited by the low thermal stability of amorphous state. Additional studies on the welding mechanism and on the weldability of amorphous alloys to various materials are in progress.
