Abstract
A pair of tubes are provided, one of greater diameter than the other so that the tubes can be telescoped together. An annular inward facing projection is formed on the outer tube for contact with the outside surface of the inner tube when the tubes are telescoped together. An annular outer facing projection is formed on the inner tube for contacting with the inside surface of the outer tube when the tubes are telescoped together. An adhesive is placed on one of the tubes for contacting with the other tube when the tubes are telescoped together. After the tubes are telescoped together weld current is conducted through the tubes to weld the annular projections to the respective opposing tube in contact therewith and at least partially cure the adhesive.
