3.5 Overview of the Welding Process

The welding control program supports the extended data encoding
specifications under the ISO 12176 standard, e.g., pipe and fitting
traceability codes. To use this capability, the desired data have to be
enabled in the configuration menu, at "Recording" (see Sect. 4.1).
All data that are relevant for the joint or for component traceability
are saved to the internal memory and can be sent to a USB stick.
The welding parameters can also be entered manually. The welding
system is microprocessor-controlled and:-
• controls and monitors the welding process in a fully automated
way, when the welder starts it after component preparation,
• determines welding duration depending on ambient tempera-
ture,
• shows all information on the display in plain text.
In the manual mode, the machine performs a classic, manual butt-
welding operation. It monitors the temperature of the heating ele-
ment, taking the desired nominal temperature that can be set using
the ñ and ò cursor keys, into account, and readjusts it as needed.
In the WeldControl mode, the machine guides the welder through
the welding process, monitors all relevant parameters, and allows en-
tering traceability data for the welded components on intuitive menu
screens. Parameters of the welding operation, component traceability
data, and possible errors are recorded and saved to memory and can
be transferred via one of two USB interface ports to a USB stick, a
USB-compatible printer, or a PC with the management and database
application DataWork.
The welder performs the butt-welding process in the following
manner:
• Pipes are clamped into the frame.
If pipes with an outside diameter smaller than the maximum
dimension of the machine are welded, select the reducer set
needed. The 8 individual inserts of the set that matches the out-
side diameter of the pipe to be welded have to be attached to
the clamps of the machine chassis using the provided bolts.
• In the manual mode, applicable welding times and pressures are
looked up in the overview tables in the appendix.
• In the WeldControl mode, the mandatory and the optional
component traceability data are entered in the menus on the
screen.
• Pipe butts are worked using the pipe facing tool.
• Pipe alignment is checked.
• The drag pressure, i.e. the minimum pressure to set the carriage
in motion and "drag" it along, is recorded at the machine.
• The pressures relevant to the welding operation are set.
• The heating element is inserted after cleaning it and checking its
temperature.
• The welding process proper is performed (see section 4), and the
operator waits for the jointed pipes to cool down.
• After the cooling time is over, pressure can be shut off from the
pipes (in the manual mode by the welder, in the WeldControl
mode automatically by the machine) and the joint can be taken
out of the chassis.
