BUTT FUSION DO'S & DON'TS
Use equipment that is clean, in good condition, regularly maintained and within required calibration.
Ensure the correct jointing parameters for the machine and pipe are known, understood and selected.
Ensure the generator is in good condition and has plenty of fuel.
Check that the heater plate is clean. Clean trimmer discs before use.
Check that the trimmer is clean and that the blades are not damaged and in the correct position for the required pipe size.
Ensure clamp liners and securing screws are of the correct size.
BUTT FUSION DO'S
Always input correct operator code and job code to allow for full traceability.
Always weld in a shelter and on a suitable board or ground sheet.
Check size, SDR and pipe material to ensure compatability.
Always ensure pipes are aligned correctly and supported on pipe support rollers to minimise drag.
Cover pipe ends to eliminate wind chill to the heater and joint interface.
Clean pipe surfaces inside and out, clean pipe ends and clamps before inserting pipe into machine.
Position pipes in clamps with the pipe marking to the top and aligned.
Wash the heater plate when cold before every welding session and perform dummy welds when hot to remove fine particles and prevent the production of fumes.
Always perform dummy welds after changing pipe size and also if the heater plate has cooled.
Ensure when trimming a continuous ribbon of material of pipe wall thickness is produced from both pipe ends before commencing feathering operation.
Always use trimmer/hotplate stands provided.
Always remove swarf from underneath pipe ends and chassis.
Visually check that both ends are completely trimmed.
Always check pipes for alignment and gaps around the entire circumference of the abutted pipes.
Always remove external bead from completed joint, bag and label with corresponding joint number for submission and inspection by the supervisor.
BUTT FUSION DON'TS
Attempt to use equipment unless trained to do so.
Attempt to weld pipes of incompatible materials or SDR.
Leave swarf inside pipe or chassis.
Introduce dirt onto trimmed pipe ends whilst removing swarf.
Touch trimmed pipe ends or fitting ends.
Remove pipes from machine before cooling time has elapsed.
Attempt to cut corners in any part of the welding cycle.
Attempt to install pipe until fully cooled.
