For mechanical connectors, alternative electric welding is used for joints in plastic polyethylene pipes when building a water supply network. Depending on the diameter of the pipe to be connected, either electrical connection parts or butt welding are used. Electric welding with smaller diameters is based on heating the base material and melting the plastic at the joint. Electric welding takes place in such a way that the parts are heated by an electric welding machine, which conducts electric current through the conductors to the resistance wires in the connecting sleeves. The current intensity and heating time are precisely determined. The required values can be entered into the machine manually or the process can be fully automatic, in which case the welding machine detects the part connected to it with wires and adjusts the welding time and current automatically. In welding parts, the essential difference is in the location of the resistance wires. In some manufacturers, the wires are partially visible on the inner surface of the part. There is a risk of damaging the wires during installation and failure of welding. In Plasson sleeves, the resistance wires are always inside the base material. In this case, they are protected when installing the pipe inside the parts. The ends of the pipes to be connected must be properly cut, cleaned and scraped or planed off the surface with the Plasson tools. The success of electric welding depends on the preparation, welding time and temperature, as well as the cooling time. Throughout the Electric Welding process, it is important that the pipes and parts to be connected do not move relative to each other. This can be easily ensured by using Plasson welding supports to lock the parts and pipes in place. In addition to machines, cutting pliers and scrapers, as well as pliers, the welding stand and, if necessary, the pipe rounding tool should be included in the basic tools for electric welding. In addition to electric welding parts, injection-molded PE pipe parts can be used, including e.g. angles, t-branches and various shrink and flange connections. The parts are connected to the pipes using electric welding parts. Ulefos Plasson electric welding parts, Automatic welding machines and planers For more than 40 years, PLASSON has been one of the world's leading manufacturers of high-quality electric welding parts. The electric welding parts manufactured by Plasson meet all the high requirements for modern pressurized water and wastewater networks. Quality combined with the high-tech SmartFuse system allows Plasson to offer the most economical and safest range of electric welding consumables on the market. Electric welding - SmartFuse: The electric welding parts together with the Plasson welding machines form the SmartFuse system, which means that the welding process is fully automatic up to a pipe diameter of 400 mm. The entire welding process is computer-controlled, which minimizes possible errors during welding and produces tight seams and a long service life.
