Abstract: A method of attaching a tube having a tube wall defining a tube channel therein to a workpiece having a workpiece wall. A workpiece opening defined by a workpiece opening wall surface is formed in the workpiece wall. A tube engagement surface is formed on the tube wall for engagement with the workpiece opening wall surface. A workpiece heated portion in the workpiece, and a tube heated portion in the tube, are heated in a non-oxidizing atmosphere by energized heating elements to a hot working temperature. The tube is subjected to an engagement motion, moving the tube engagement surface relative to the workpiece opening wall surface. While the heated portions are at the hot working temperature, and while the tube is subject to the engagement motion, the tube engagement surface is pressed against the workpiece opening wall surface, for plastic deformation of the heated portions, to create a metallic bond.
