Abstract
Two solid copper pieces are assembled by welding without filler metal. The pieces both have a projection which are placed facing and in contact with one another, before the pieces to be assembled are placed on the welding press. Welding is performed by passing a very high intensity current for a short period of about one tenth of a second under very high pressure. The welding operation prevents any annealing of the copper.
