Using tooling specifically designed for Electorfusion welding is key to achieving quality welds. Equipment may vary depending on the product welded or the diameters being fused but should generally include the following:
Pi Tape - to measure the outside diameter of the pipe. It is key to check pipe is the correct size for the fitting being installed and that it has been manufactured to specification
Pipe cutting equipment - all pipe ends need to be cut straight to ensure a quality weld
Marking pencil or pen - details like witness marks for correct insertion depth, weld and cool times must all be marked clearly and permanently on the pipe during welding
Peeling tools - the area to be welded is prepared for fusion with the removal of a specific depth of plastic from the pipe surface to be sure fusion can successfully occur
Welding wipes - having contaminants like water, sweat, oil, dirt, sunscreen and lint from clothing on the pipe can create a barrier that prevents complete fusion. Manufacturer approved welding wipes remove these contaminants
Re-rounding tools - pipe needs to be round in order to make good contact with all surfaces of the fitting it is being joined with. Pipe can become oval when stored, transported or stacked and needs to be re-rounded to achieve a quality weld
Pipe alignment clamp - pipe must be held firmly in place during the entire weld and cool time to ensure a quality weld.
Power generator – generators must be capable of supplying the required power to weld the fitting. Documentation with each EF fitting will note its power requirements.
Electrofusion welder with correct leads and sufficient output power to weld the required fitting.
Electrofusion must be carried out by certified installers. For more info visit www.plasson.com.au
