Abstract
A method for resistance welding/brazing a tube to a container. A tube is obtained having an axially-extending first portion and a tube form which extends transversely from the first portion. A container is obtained having an orifice. A support tool is obtained with an expandable head. The tube form is positioned proximate the outer surface of the container and surrounding the orifice. The unexpanded head of the support tool is passed through the orifice of the container. The head of the support tool is expanded inside the container. The inner surface of the container is supported with the expanded head of the support tool. A resistance current path is created through the tube form and the container creating a weld/braze zone which includes at least some of the tube form and at least some of the container.
