Abstract

The use of resistance spot welding (RSW) technology for joining Ti₄₀Zr₂₅Ni₃Cu₁₂Be₂₀ metallic glass was investigated. The microstructure obtained from the welded BMG sample was studied. Joint without precipitates was prepared with welding current of 5.0 kA for 2 cycles. A fully coupled thermal–electrical–mechanical finite element model (FEM) was developed to complement the experimental study. The simulated results agree well with the measurements. The effects of key process parameters such as welding current and welding time on the evolvement and microstructure of the weldment were determined and discussed. Moreover, the critical cooling rate for preserving the amorphous state in the weld fusion zone is determined to be approximately 1 × 10³ K·s⁻¹.
