Abstract

Resistance tube closure welds, referred to as pinch welds, are used to reliably seal small stainless steel tubing. The pinch welding process, discussed in detail by Thomas et al [1], involves applying a load to force electrodes together to collapse the tube, sometimes in the presence of confining dies which prevent lateral expansion. Electric current is injected through the electrodes to soften the tube through Joule heating. The resulting hot plastic deformation causes contact and welding of the inner surfaces of the tube.
