End Of Welding; Fully Manual Butt-Welding Process - HURNER Weld Control 315 2.0 Manual De Instrucciones

Depending on the welding standard used or on information
provided by the pipe or fitting manufacturer, a cool-on time
may be required during which the new joint must not be ex-
posed to external forces. This, however, is not monitored by
the hydraulic, control, and data logging unit, for which the
welding has to be considered finished when the 7

End of Welding

The welding is finished at the end of the successful joining
and cooling stage. The machine releases the pressure on the
pipes automatically.

Fully Manual Butt-welding Process

When you want to weld fully manually, the machine
has to be switched to Manual Mode. To do so, press
the ï and ð arrow keys simultaneously while "Next
Info
Welding" is showing on the screen. In the manual
mode, the display screen looks like what Display 31
shows.
When installing possibly required reducers for com-
ponents with a smaller diameter, make sure they are
correctly positioned in the clamps, as described in
Important
the Important note in Sect. 3.4.
In a fully manual welding process, pipe facing, pipe align-
ment check, determination of the pressure to "drag" the
carriage along and of the joining pressure (i. e., the maxi-
mum pressure of the welding, reached during bead build-
up and joining) have to be performed in the exact same way
as in the Weld Control Mode (see the relevant sub-sections
of Sect. 4.3). The only difference is that the display does not
instruct as to what to do. It works as a digital gauge indicat-
ing the actual pressure applied to the pipes (see Display 31).
It also shows the nominal temperature the welder has to set
and the actual temperature of the heating element, and it
monitors and controls the temperature throughout the pro-
cess. The parameters for proper welding have to be looked
up in the welding value tables in the appendix.
The tables in the appendix are valid only for
straight joints! Contact the manufacturer if
the welding system is meant to be used for a
Caution
non-straight joint. This kind of welding opera-
tion absolutely requires a prior briefing by the
manufacturer or an authorized service partner.
The farther the carriage mover lever is pushed to the
left, the faster the carriage closes in and the faster
pressure increases. The farther it is pushed to the
Info
right, the faster the carriage of the machine moves
apart, and the faster pressure decreases.
