3.5 Overview of the Welding Process

The welder performs the welding process in the following manner:
• Applicable welding times and pressures are looked up in the
overview tables in the appendix.
• 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.
• 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 shutt off from the
pipes and the joint can be taken out of the chassis.
