METHOD FOR METALLURGICALLY ATTACHING A TUBE TO A MEMBER

摘要

A method for metallurgically attaching a tube (32) to a member (18). A member (18) having a wall (20) is obtained. The wall (20) includes opposing first and second sides (22, 24) and includes a partial extrusion (26) extending above the first side (22). The partial extrusion (26) has a through hole (28). A tube (32) having an end portion (34) is obtained. The tube (32) and the member (18) are positioned with the end portion (34) contacting the second side (24) of the wall (20) proximate the partial extrusion (26). A resistance welding current path is created through the tube (32) and the member (18) proximate the end portion (34) and the partial extrusion (26), and the end portion (34) is relatively moved into and deformingly against the partial extrusion (26) creating a weld zone (36) which includes at least some of the end portion (34) at least some of the partial extrusion (26).
