those pipe codes state different sizes and/or Stan-

code error is triggered since these welding param-
eters must be identical for both pipes.
All data can be entered by using the cursor keys and con-
firming by pressing the START/SET key or can be scanned
from a bar code with the optional handheld scanner or an
RFID card using the transponder reader. One exception is
the weather (see Display 13), which is presented as a list in
which the applicable conditions can be selected by press-
ing ñ or ò and confirmed, by pressing the START/SET key.

Performing the Butt Welding Operation

To start welding, clamp the pipes into the machine chassis.
Use the appropriate reducer inserts if the component size is
smaller than the basic machine chassis. If Tees, elbows, and
other short pipeline components are planned to be weld-
ed, reconfigure the machine chassis as described in Sect. 3.4.
Then, to launch the welding process, press the START/SET
key.
To allow not only jointing a tee, crosspiece, and
Y branch-off to a straight length of pipe, but, rath-
er, manufacturing them, likewise, to manufacture

an elbow of segments jointed to each other at an
angle, the system has to have pipe segment weld-
ing enabled in the configuration menu (refer to
Sect. 4.1.2). In that case, as part of the input or con-
firmation of the component parameters, the weld-
ing system prompts the user for the kind of joint-
ing operation at hand: straight or sergmented-bend
pipe joint or production of a tee or crosspiece ("X")
or Y branch-off. Select the appropriate kind of joint
in the displayed listing using the ñ and ò cursor
keys and confirm your selection by pressing the
START/SET key. If you select a welding type other
than a straight pipe joint, the system displays anoth-
er prompt for entering details on this non-straight
jointing operation and, possibly, the step in the pro-
tocol that the jointing in hand is going to represent.
If the wrong kind of jointing set-up or the
wrong process step in the protocol is entered
here, the satisfactory quality of the finished
