ABSTRACT:
A method of and apparatus for joining a small diameter tube to a large diameter tube. An indentation tool is used to inwardly deform the wall of a tube from the outside into the internal bore of the tube. The resulting indentation formed has an open end sized to receive the small diameter tube. The small diameter tube is then located within the indentation and mechanically joined by brazing or soldering such that the axis of the portion of the small diameter tube within the large diameter tube is roughly parallel to the axis of the large diameter tube.
