ABSTRACT:
A method for metallurgically joining a tube to a member. A tube having a flange is obtained, and a member is obtained. A welding/brazing electrode wheel is obtained having an axis of rotation and having a rim. The tube and the member are positioned with the flange contacting the member directly and/or indirectly through an intervening welding/brazing joining material. The rim of the electrode wheel is positioned in direct contact with the flange. A resistance welding/brazing current path is created through the flange and the member using at least the electrode wheel creating a seam weld/braze zone which includes at least some of the flange and at least some of the member. During the current path creation step, the electrode wheel is rotated about the axis of rotation.
