1. The influence of voltage fluctuation on the interface quality. The resistance value of the resistance wire in the given electric fusion pipe fittings in the PE pipe welding machine is constant. Therefore, the heating power of the resistance wire depends entirely on the voltage provided by the power supply, so the quality of the welding joint will deteriorate due to the influence of voltage fluctuation on the heating power.
2. The influence of welding time on the interface The range of heat required for each specification of electric fusion pipe fittings is fixed, too much or too little heat will have a fatal impact on the welding quality, and when the welding voltage and pipe resistance are fixed Under the premise that the welding time is the only determinant of the heat of the pipe fittings, it is necessary to accurately control the ambient temperature of the welding time to reduce the impact on the normal operation of the PE pipe welding machine.
3. The change of the ambient temperature during the use of the PE pipe welding machine directly affects the heat transfer conditions in the welding zone, which in turn affects the quality of the welding. Therefore, the PE pipe welding machine must be able to monitor the ambient temperature and automatically adjust the output parameters according to the deviation result. Adjust accordingly.
4. The influence of bad operation on the quality of welding interface. The so-called bad operation of the PE pipe welding machine means that the cleaning or scraping of the pipe during welding does not meet the specifications (especially the socket is not assembled in place, the end of the socket has a large slope, etc.), which requires the operator to have certain Welding knowledge. On the other hand, errors occur when inputting welding parameters, which should be avoided by setting the PE pipe welding machine itself.
