Dissimilar Resistance Welding of C1020/SUS304 Plates Using Zr–Based Metallic Glass Ribbons as Interlayers

Abstract

Dissimilar resistance welding of C1020/SUS304 plates was performed with and without interposing Zr₅₅Al₁₀Ni₅Cu₃₀ metallic glass ribbons as interlayers. The joint strength of the welded specimens without the metallic glass ribbons was lower than that of those with the ribbons, when a higher electrode load was applied. Similar load–displacement curves of the tensile shear tests were obtained with interposing the glassy ribbons when lower electrode load was applied. The number of the welded specimens exhibiting joint strength higher than 1000 N increased when a lower electrode load was applied and the metallic glass ribbons were interposed. The reproducibility of load–displacement curves of the tensile shear tests was increased by the glass transition to a supercooled liquid of the metallic glass ribbons upon resistance heating during welding.
