Abstract
A method for metallurgically joining a tube to a member. A tube is obtained having a longitudinal axis and having an end portion, wherein the end portion includes a fold, and wherein the fold includes longitudinally-spaced-apart first and second fold portions. A member (such as, but not limited to, a plate or a second tube) 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.
