Capacitor Energy Storage Welding of Ni₆₃Cr₁₂Fe₄Si₈B₁₃ Amorphous Ribbons

Abstract:

Ni-based metallic amorphous alloys in ribbons shape are used in the manufacture of electrical resistances due to their high electrical resistivity, a value that does not change with temperature. The production of such resistances involves joining processes of amorphous ribbons. The amorphous alloys are difficult to weld by conventional melting processes, even in the presence of inert gas. Consequently, this paper presents the research carried out regarding the capacitor energy storage welding technique of Ni₆₃Cr₁₂Fe₄Si₈B₁₃ amorphous ribbons. The structural analysis was done by microscopy, X-ray diffraction, and differential scanning calorimetry, and the mechanical behavior was determined by nanoindentation. The joints obtained showed that the proposed welding technology is appropriate for this type of joint.
