Electrofusion welding is a type of resistive implant welding used to join pipes seamlessly. This process involves a fitting with embedded metal coils, which is placed around the ends of the pipes to be connected. When an electric current passes through the coils, resistive heating occurs, melting small portions of both the pipe and fitting. As the material cools and solidifies, a strong, durable joint is formed.

This technique is most commonly used for joining polyethylene (PE) and polypropylene (PP) pipes, making it the preferred method for connecting PE pipes in various applications. Due to its ability to consistently produce robust and reliable joints, electrofusion welding is widely used in the construction and repair of gas pipelines.

The strength of the joint depends on several process parameters, such as temperature, pressure, and heating time. To ensure optimal results, a consistent and precise joining procedure is essential. Electrofusion welding offers a dependable solution for creating long-lasting, leak-free connections in critical piping systems.

Electrofusion fittings are widely used in gas, water, and wastewater applications, providing reliable and durable connections for piping systems in these critical industries.
