TL;DR: In this article, the effects of electrode materials and process parameters on joint strength and nugget size were investigated for small-scale resistance spot welding (SSRSW) and the welding current ranges for the sheet metals were determined based on the minimum current that produced a required diameter and maximum currents that did not result in electrode-sheet sticking or weld metal expulsion.
Abstract: The resistance weldability of 0.2-mm-thick sheet aluminum, brass, and copper in small-scale resistance spot welding (SSRSW) was studied. The effects of electrode materials and process parameters on joint strength and nugget size were investigated. The welding current ranges for SSRSW of the sheet metals were determined based on the minimum current that produced a required nugget diameter and maximum currents that did not result in electrode-sheet sticking or weld metal expulsion. A qualitative analysis indicated that resistance weldability of the metals is not only determined by their resistivity (or thermal conductivity) but is also affected by other physical properties (such as melting point, latent heat of fusion and specific heat).

18 Jun 2002TL;DR: In this article, a solid electrolytic capacitor has a structure where respective anode sections of capacitor elements are joined by resistance welding via a through hole formed in the anode lead frame.
Abstract: A solid electrolytic capacitor of the present invention has a structure where respective anode sections of capacitor elements are joined to an anode lead frame by resistance welding via a through hole formed in the anode lead frame Current thus collects to the through hole during the welding to break a dielectric oxide film layer to expose aluminum foil, and the molten aluminum collects into the through hole Stable welding work is therefore allowed without splashing the aluminum, and a solid electrolytic capacitor having high welding strength, high reliability, and reduced ESR can be obtained
