Abstract:
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).
Abstract:
A method for manufacturing a tubular assembly (10). A first tube (14) is obtained. A first tubular connector (18) having first and second end portions (20, 22) is obtained. The first end portion (20) is metallurgically attached to the first tube (14). A tubular member (28) having a third end portion (30) is obtained. At least one of the second and third end portions (22, 30) includes an annular outward fold (22) including spaced-apart first and second fold portions (34, 36). The first tubular connector (18) and the tubular member (28) are positioned with the second end portion (22) aligned with and contacting the third end portion (30). A resistance welding current path is created through the first tubular connector (18) and the tubular member (28) proximate the second and third end portions (22, 30) and the second and third end portions (22, 30) are relatively and deformingly moved together, creating a weld zone which includes at least some of the second and third end portions (22, 30).
