Amorphous alloys have attracted considerable attention as new structural materials due to their excellent mechanical properties, high wear and corrosion resistance, magnetic properties, and electrical resistivity. However, most of them become brittle by crystallization, structural relaxation, or by separating intermetallic phases during heating. That is why the traditional methods of melt welding based on the introduction of a large amount of heat and the production of intermetallic phases on the interface between the seam and the thermally influenced area are not suitable for joining these materials. Such welding methods can lead to the destruction of the amorphous structure and to the worsening of the useful properties of the welded joints.In this paper, a new method of joining amorphous alloys is investigated based on the modification of the welding energy for different values of the capacity of the capacitor, keeping constant the pressing force and the transformation ratio. The examination of the quality of the welded joints was done by macro graphic analyzes, mechanical tests, and calorimetry with differential scanning. (Differential Scanning Calorimeter)
