P1: Approach and preheating pressure,P2: Maximum heating pressure,
P5: Welding pressure,
Pt (Drag pressure): pressure necessary to overcome the friction of the machine. It must be measured by the operator
with the pressure gauge of the hydraulic unit.
t1, t2, …, t5: duration of phases 1,2, …, 5.
1- Approach and Preheating Phase. Bring the edges to be welded closer with the thermal element at
the pressure (P1+Pt) so that the edge reaches the dimension provided for by the standard used.
2- Heating Phase. Reduce the pressure to the maximum value P2, sufficient to maintain contact of the edges of the
pipe with the thermal element, for the time t2
Note: The operator, by reducing the pressure, must be careful not to detach the edges from the thermal element. If
this happens, the welding must be repeated.
3- Phase of Extraction of the thermal element. Remove the thermal element at the maximum time t3, without damaging the edges of the two elements to be welded.
4- Phase of reaching the welding pressure. Put the edges in contact, progressively increasing the pressure up to the value (P5+Pt), in time t4. Prevent the soft material from coming out of the surfaces that were approached.
5- Welding Phase. Keep the edges in contact under pressure (P5+Pt ) for time t5.
Do not use water or compressed air to accelerate the cooling of the fusion. If necessary, protect the weld from
rain, wind or excessive solar radiation.
