agru SP 315-S User’s Manual
While the welding procedure is starting, with or without pre-heating, the
machine controls and monitors constantly the temperature of the heating
element and the welding force and time. Nominal values and tolerance
ranges are defined by the key data for the welding operation previously
entered or confirmed. If a value is not within the applicable tolerance
thresholds, the machine shows an error message to this effect and the
welding process is aborted.
4.6.4 Heat-Soaking
Phase
In the first welding phase, the pipes close
in on the heating element with the defined
welding force and are thereby war med.
During the entire duration of the heating
phase, they continue to soak heat from the
heating mirror without touching it.
On the touchscreen, the welding progress
diagram indicates in which phase the weld-
ing currently is (green LED icon). In case
of malfunction, the welding process can be
aborted by touching the “Cancel” button. If
the machine detects a malfunction, the color
of the LED icon for the appopriate phase
changes from green to red.
4.6.5 Change-over
Phase
At the end of the heat-soaking phase the
carriages are moved apart automatically.
The heating mirror is removed from in-
between the pipes, and the carriages close
in again; both actions occur automatically.
The welding progress diagram on the touch-
screen indicates in which phase the welding
currently is (see Display 15).
The welder has to monitor the change-
over and must abort welding by touching
“Cancel”, in case a malfunction occurs.
4.6.6 Joining
Phase
In the joining phase (or, fusion phase) the
machine increases the applied force in ac-
cordance with the force ramp calculated for
the weld. This phase is also indicated on the
touchscreen panel.
4.6.7 Cooling
Phase
When the full joining force is reached,
the machine moves on automatically to
the cooling phase (see Display 16). The
cooling-down is displayed as a countdown.
During cooling, the applied joining force is
constantly monitored.
4.6.8 End
of
Welding
After a successful welding operation, which
can also be recognized in the welding
diagram, the applied force is removed from
the pipes, and they can be taken out of the
clamps.
