PURPOSE: A copper pipe joining method is provided to securely connect a copper pipe to a connector without welding because the overlapped part between the connector and the copper pipe is pressed by a presser. CONSTITUTION: A copper pipe joining method is as follows. The burrs in the end of copper pipes(2) are eliminated, and foreign substances are eliminated from the contact parts of a hollow connector(1). An adhesive(3) for metal is spread on the contact parts of the connector and the copper pipes. The copper pipes are inserted into both ends of the connector. The connection parts of the connector, in which the copper pipes are inserted, are pressed by a presser. The pressed parts(10,20) of the connector and the copper pipes are overlapped.
