Electrofusion Welding

In electrofusion welding, a coupler (electrofusion fitting) is placed over the joint at the peeled and cleaned joint of two pipe ends.

The electrofusion control unit energizes the heating coil integrated in the electrofusion coupler. This heats up the plastic in the welding zone to such an extent that it melts.

At the end of the material and product-specific welding time, the welding zone cools down again below the melting point of the plastic. The fitting and the pipe parts are inseparably fused together and form a gas-tight connection.
