During the use of the PE pipe welding machine, improper operation and environmental changes may affect the quality of the electrofusion interface. Reasonably avoiding these factors can prolong the service life of the PE pipe welding machine.
1. The influence of voltage fluctuation on the interface quality. The resistance value of the resistance wire in the electric fusion pipe given in the PE pipe welding machine is certain. 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 be deteriorated due to the influence of the voltage fluctuation on the heating power.
2. The influence of welding time on the interface The heat range required for each specification of electrofusion pipe fittings is fixed. Too much or too little heat will have a fatal impact on the welding quality, while the welding voltage and pipe resistance are fixed. Under the premise that the welding time is the only determinant of the heat generation of the pipe fittings, the ambient temperature of the welding time must be accurately controlled 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 area, which in turn affects the quality of 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 results. 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, on the one hand, means that the cleaning or scraping of the pipe does not meet the specifications during welding (especially the socket and socket assembly is not 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 is the error that occurs when inputting the welding parameters, which should be avoided by the settings of the PE pipe welding machine itself.
