Performance of Fast Butt Fusion Jointing
A high productivity butt fusion welding process has been developed by Fusion Group. The process was evaluated on PE80 and PE100 pipe materials in sizes up to 400mm and compared against butt fusion joints prepared under conventional Water Industry conditions. It was found that there was a threefold increase in productivity with all joints failing in a totally acceptable ductile manner. However, the short soak time of the process resulted in significantly reduced weld beads and it was felt there was less scope for pushing out potential contamination from the weld interface. Modified conditions were developed for PE80 pipe that combined the productivity benefits with the weld bead sizes and performance characteristics of conventional butt fusion joints. Similar modified welding conditions were applied to PE100 pipe but this found to be less successful.
