A method for welding/brazing a tube to a member. The tube has an axially-extending first portion and has a tube form which extends transversely from the first portion. A filler material is obtained. The tube, the member and the filler material are positioned such that the filler material contacts the tube form and the member. A resistance current path is created through the tube, the filler material and the member which melts at least some of the filler material creating a weld/braze zone which includes at least some of the tube, at least some of the member, and at least some of the filler material.

Method for resistance welding/brazing a tube to a member

A method for joining a tube to a member. A tube having a flange is obtained, and a member is obtained. The tube and the member are positioned with the flange contacting the member either directly or indirectly through an intervening joining material. The tube and/or the member are locally heated proximate the contact of the flange and the member without substantially heating the tube and/or the member apart from proximate the contact of the flange and the member. In one example, the local heating is welding, with or without a filler material, such as resistance welding, laser-beam welding or electron-beam welding. In another example, the local heating is brazing. In an additional example, a curable adhesive joining material is placed on the flange and/or the member, wherein the adhesive is located between and directly contacts the flange and the member, and wherein the local heating cures the adhesive.

Method for joining a tube to a member

A method for metallurgically joining a tube to a member. A tube having a flange is obtained, and a member is obtained. 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 flange and/or the member is segmented and their contact is a segmented contact at spaced-apart contact areas between the flange and the member. A resistance welding/brazing current path is created,through the tube and the member at a first contact area creating a first weld/braze zone which includes at least some of the flange and at least some of the member. Then, a resistance welding/brazing current path is created through the tube and the member at a different second contact area creating a second weld/braze zone which includes at least some of the flange and at least some of the member.
