Overview of the Welding Process

The welder performs the butt-welding process in the fol-
lowing manner:
• Applicable welding times and pressures are looked up in
the overview tables in the appendix.
• Pipes are clamped into the chassis frame.
If pipes with an outside diameter smaller than the maxi-
mum dimension of the machine are welded, select the
reducer set needed. The 8 individual inserts of the set
that matches the outside diameter of the pipe to be
welded have to be attached to the clamps of the ma-
chine 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 components to
cool down.
• After the cooling time is over, pressure is shut off from
the pipes and the joint can be taken out of the chassis.
