Abstract
A method of forming a metallic container by placing body and lid portions together, keeping parts of the body and lid portions in contact with one another, and vibrating the lid with respect to the body, thereby generating frictional heat to form a friction metallic weld therebetween. Apparatus for attaching the lid and body portions of the metallic container includes a body supporting base, an assembly to support a flange of the body, a sonotrode to contact a flange of the lid so that wherein the flanges of the lid and body are held together between the support assembly and the sonotrode. A motor vibrates the sonotrode relative to the support assembly to thereby move the flanges relative to one another generating sufficient frictional heat to create a friction metallic weld therebetween.
