6.2 Procedure
6.2.1 Secure, Face and Align
Starting with clean pipe and fittings (see 5.3), place the
fusion ends of the pipe and fitting into the clamps of the
fusion machine.
Figure 6.2.1.1 Place pipe ends in open fusion machine clamps
Do not force components into the open clamps of the
machine.
Ensure there is enough material exposed from the fitting and
pipe ends to allow enough material for fusion following
facing.
Secure Clamps, and bring ends together to check alignment.
Tighten clamps, if required, to round high pipe. Do not loosen
clamps to round low pipe. The pipes

Figure 6.2.1.3 Checking alignment of pipe ends. Adjust as
required.
Insert the facing tool between the pipe ends and apply
reasonable pressure to the facing tool to ensure parallel and
smooth mating surfaces.
Figure 6.2.1.4 Insert Facing tool between pipe ends
Facing is complete when continuous ribbons of material are
removed from each turn of the facing tool. If fusion
equipment is equipped with facing stops, remove material to
the stops.
Figure 6.2.1.5 Remove material with facing tool
Remove the facing tool, remove any shavings and debris and
bring the pipe ends together to confirm alignment.
Do not touch surfaces with bare hands after facing. This will
contaminate the fusion.
Figure 6.2.1.5 Remove facing tool
Bring the ends together to confirm alignment. There should
be no gaps between the pipe ends, and the ends shall be
concentric and round. If adjustments to alignment are
required (clamp tightening, repositioning, etc.), reface the
ends and reconfirm alignment afterwards.
