摘要： PROBLEM TO BE SOLVED: To prevent an abnormal heating from occurring, even when a short- circuiting is caused by first detecting the initial value of an electric current for fusion bonding when the electric current is applied to an electrofusion joint at a specified voltage. SOLUTION: When a fusion bonding process is initiated by pressing a start button, a switching means 1 is turned on by a control signal from CPU 6 and an electric current for fusion bonding at a constant voltage is applied to an electrofusion joint 2 from a constant voltage circuit. In turn, CPU 6 calculates a resistance based on an electric current value measured by an electric current measuring means 4 and stores a set time corresponding to the resistance in RAM 8 after obtaining the time from ROM 7. In addition, CPU 6, referring to a clock generator 9, stores an electric current value when a reference time reaches the level of time when the voltage is stable in RAM 8, if the reference time arrives at such a level. Thus CPU 6 controls an electric current adjusting means 3 so that the electric current value stored in RAM 8 is maintained as it is until an energization time set thereafter elapses. The termination of the energization is performed by the control signal from CPU 6 when the reference time reaches the set time.

摘要： PROBLEM TO BE SOLVED: To perform fusion of an electro-fusion joint of a large diameter by the use of normal generator and connector without requiring a large amount of energy, supply sufficient electric energy by the use of a large-sized power generator, and prevent melting of the joint and a synthetic resin pipe. SOLUTION: A reception port of an electro-fusion joint 1 into which a synthetic resin pipe 2 is inserted is divided into plural fusion areas A to D. Heating wires are independently embedded in the fusion areas A to D in the form of coils. The terminals of all the wires are arranged in plugs 4. When a connector 6 is inserted into the plug 4 and current is carried, the current reaches first to the wire in the area A, and an inner peripheral surface of the area A is heated and melted. After a specified time of current carrying, the current reaches sequentially the areas C, B, D. Power and current carrying time to be controlled by a controller 5 is decreased step by step.

摘要： PROBLEM TO BE SOLVED: To improve the operational efficiency in a fusion joining method for thermally fusing a synthetic resin tube and an electrofusion joint embedded at its joining face to the synthetic resin tube with a heating wire through the electrification to the heating wire, by obtaining a sufficient fusion strength without removing a soil on the outer surface of the tube to dispense with a soil removing process. SOLUTION: At the fusing process, a vibrator 4 is fixed on a joint 1 with a band 5 and a start switch of a controller 3 is depressed to start electrifying the joint 1. After a preset period of time, the electrification is stopped while the motor of the vibrator 4 is activated for its vibration which is to be transmitted to the joint 1. A soil is thus dispersed through the mixing in the fused interfaces.
