Electrofusion welding is another technique used for joining thermoplastic pipes, similar to butt fusion welding. However, unlike butt fusion welding, which involves heating the entire pipe ends and then bringing them together, electrofusion welding uses electrical resistance to heat a specifically designed fitting, causing it to melt and fuse with the pipe. Electrofusion welding is commonly used for joining pipes in applications such as water and gas distribution, as well as in industrial settings. It offers advantages such as precise control over the welding process, the ability to weld in tight spaces, and the capability to monitor and record the welding parameters for quality assurance. This method is particularly suitable for joining polyethylene (PE) pipes, and it is known for producing reliable, leak-free joints with excellent strength.
