PURPOSE:To raise the quality and yeild of products as well as to prevent maloperations by a method in which a lock mechanism to automatically control heating and bonding operations is mechanically built in, and before or after the lapse of a given time period, the succeeding operations are locked. CONSTITUTION:A pipe clamp 10 or a socket clamp 50 is slid toward the counterpart one by means of a handle 23 or 63, and a heater block 100 is contacted with and fitted into a pipe P and a saddle S. After the periphery of the pipe end and the inner surface of the socket are heated for a given period of time t1 by the heater, both the clamps are separated from the heater block and the heater block 100 is quickly removed out. The inner surface end of the socket S is contacted with inserted with the peripheral end of the pipe P and bonded. After the bonding for a given period of time t3, the pressing force is released, the joint faces are cooled, and the socket S is completely hot-bonded with the pipe P. In short, unless a given period of time is passed or after a given period of time is passed, the succeeding operations are stopped to prevent the occurrence of maloperations. |
