METHOD FOR METALLURGICALLY JOINING A TUBE TO A MEMBER

摘要

A method for metallurgically joining a tube to a member. A tube (118) is obtained having a longitudinal axis (120) and having an end portion (122), wherein the end portion includes a fold (124), and wherein the fold includes longitudinally-spaced-apart first and second fold portions (126 and 128). A member (such as, but not limited to, a plate or a second tube (130)) is obtained. The tube and the member are disposed with the end portion contacting the member. A resistance welding current path is created through the tube and the member proximate the end portion and the end portion is relatively longitudinally moved deformingly against the member creating a weld zone which includes at least some of the end portion and at least some of the member.
