Abstract

PURPOSE:To obtain a fixed and stable fused state even if an atmospheric temperature is low, by correcting supply electric energy to a heater by measuring a circumferential temperature of a molten part. CONSTITUTION:At the time of joining of pipe members 1, 1 and joint member 2 with one another, a heater 3 is provided on a surface side of the joint member coming into contact with the pipe member. The heater is connected with a control power source part 4 which changes supply electric energy through a measured value of a temperature of the circumference of a heating part by a temperature sensor. In other words, when an atmospheric temperature is normal, power is supplied to the heater only during a normal power supply period of time. On the one hand, when the atmospheric temperature is extremely low, the normal power supply period of time is corrected. A device, for example, wherein a time is made longer than usual to supply predetermined electric energy, is adopted for the correction, which is executed according to software stored in a memory 26 by a microcomputer 9.

電気溶着装置が提供されている（例えば、特開昭５８−
１３１０２５号公報）。(Prior art) Conventionally, when joining a pipe member made of a thermoplastic material such as polyethylene and a joint member, a heating coil is attached to the surface of the joint member that contacts the pipe member, and a current is applied to the heating coil. There has been provided an electric welding device that welds a joint member and a pipe member by increasing the temperature of the joint member to a predetermined temperature by flowing water (for example, Japanese Patent Application Laid-Open No. 1983-1999)
131025).

（発明が解決しようとする問題点） しかるに、この種の電気溶着装置は、外気温に関係なく
電力供給時間を設定するものであるから、外気温が非常
に低い時には電力供給が十分でなく、確実な溶着状態を
得ることができないといった問題があった。(Problems to be Solved by the Invention) However, this type of electric welding device sets the power supply time regardless of the outside temperature, so when the outside temperature is very low, the power supply is insufficient. There was a problem that a reliable welded state could not be obtained.

（問題点を解決するための手段） 本発明に係わる電気溶着装置は、パイプ部材と継手部材

続されたものである。(Means for Solving the Problems) In the electric welding apparatus according to the present invention, when joining a pipe member and a joint member, a heating element is provided on the surface side of the joint member that contacts the pipe member, and the heating element is connected to a control power source whose power supply is changed depending on the measured value of the surrounding temperature.

（作用） 外気温が通常の時には、加熱要素は通常の電力供給時間
だけ電力供給される、一方外気温が非常に低い時には通
常の電力供給時間が補正される。Operation: When the outside temperature is normal, the heating element is powered for the normal power supply time, while when the outside temperature is very low the normal power supply time is compensated.

この補正は、例えば所定の電力量を供給するのに通常よ

よりも小さい電力量を供給する手法がとられる。This correction can be applied, for example, to a method that requires a longer time than usual to supply a predetermined amount of power, or a method that requires a smaller amount of power than the normal amount of power supplied for a certain period of time after the start of power supply. A method is used to supply the amount.

In other words, in Fig. 3, preheating is performed at a voltage lower than the voltage normally applied (voltage to 1 of the normally applied voltage) for a certain period of time ('rt seconds) from the start of energization, and after 73 seconds it shifts to normal heating. Figure 4 shows a certain period of time (T, 'seconds) from the start of energization.
