The fusion jointing process consists in transmitting precisely defined thermal energy to the pipe and fitting ends being joined by means of half-shell heating elements. At the same time an elastic, pressurised bladder supports the inside surface of the fusion zone in order to prevent the formation of an internal fusion bead.

Fully automatic process control of the fusion jointing process with a fusion jointing machine developed in-house by GF Piping Systems permits very simple handling and reproducible fusion quality.
