What is the Difference Between Electrofusion and Hot Melt of PE pipe Fittings

There is a difference in connection. The PE pipe is connected by an electric fusion welding machine. During hot melting, the copper wire inside the welding machine is energized, and then the inner and outer walls of the PE pipe are heated through the pipe fittings. When a certain temperature is reached, they can melt and bond together. The thermal fusion of the PE pipe is completed by a hot fusion welding machine, and the equipment heats the butt surface of the pipe, and the connection is completed after reaching a certain temperature.
