Heating Stage; Change-Over And Jointing - Hürner EasyWeld 110 Manuel Utilisateur

During the bead build-up, the force F
This force has to be looked up in the tables in the appendix.
In case of joints at an angle, instead of F use the com-
puted force F (see "Important" paragraph at the end of
α
Sect. 5.1).
Continue turning the hand wheel until the force indicator
on the right-hand side of the machine indicates the force
level valid for F .

The bead build-up stage is completed when the weld bead
that is forming reaches the height indicated in the tables in
the appendix.

Heating Stage

At the end of the bead build-up stage, the force must be
reduced to F , as previously looked up in the appendix. To
2
do this, turn the hand wheel in the opposite direction. In
case of joints at an angle, instead of F use the com-
puted force F
(see "Important" paragraph at the end of
α
Sect. 5.1).
The force thus set has to be constantly applied in the heating
stage. The heating stage is completed after the duration that is
indicated for t in the appendix.

Despite the reduced force, the contact of the com-
ponents and the heating element must be ensured
throughout this stage. It must not be lost anywhere
Important
on the compoment circumference. If so, abort and
repeat the welding operation.

Change-over and Jointing

When the heating stage is completed, turn the hand wheel
back to remove the components to be joined from the heat-
ing element, remove the heating element from in-between
them and bring the components in contact with each other
using the hand wheel.
The longest acceptable duration for this stage of the weld-
ing process is the one indicated for t
appendix.
Immediately after contact is established between the com-
ponent butts, the jointing force has to be reached. Build-
ing this force, by continuing to turn the hand wheel until
the force indicator shows the value for F
as a consistent and linear increase. F
case of joints at an angle, instead of F use the com-
puted force F (see "Important" paragraph at the end of
α
Sect. 5.1).
