Abstract
A method for metallurgically attaching a tube to a member. A member having a wall is obtained. The wall includes opposing first and second sides and includes a partial extrusion extending above the first side. The partial extrusion has a through hole. A tube having an end portion is obtained. The tube and the member are positioned with the end portion contacting the second side of the wall proximate the partial extrusion. A resistance welding current path is created through the tube and the member proximate the end portion and the partial extrusion, and the end portion is relatively moved into and deformingly against the partial extrusion creating a weld zone which includes at least some of the end portion and at least some of the partial extrusion.
