The quality of the electrofusion interface may be affected by improper operation and environmental changes during the use of the PE pipe welding machine. Reasonably avoiding these factors can prolong the service life of the PE pipe welding machine. There are the following four factors that affect the normal operation of the PE pipe welding machine.
The resistance value of the resistance wire in the given electrofusion pipe fitting in the polyethylene pipe welding machine is certain. Therefore, the heating power of the resistance wire completely depends 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.
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, and on the premise that the welding voltage and pipe resistance are fixed, the welding time is the pipe fittings. The only determinant of heat generation, so the welding time and ambient temperature must be accurately controlled to reduce the impact on the normal operation of the PE pipe welding machine.
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 make corresponding adjustment of the output parameters according to the deviation results.
The so-called bad operation of polyethylene 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, errors occur when inputting welding parameters, which should be avoided by the settings of the PE pipe welding machine itself.
