3. Functional Description
Basically the international and national guidelines are to be followed.
The plastic pipes are clamped by means of the clamping devices.
Then the front sides of the pipes are cut plane and parallel by means of the planer and the misalignment
of the pipes is checked.
The heating element is inserted and the pipes are pressed against the heating element under defined
adjusting pressure. This process is called “adjusting”.
After the prescribed bead height being reached, pressure is reduced, the heating time begins. The
function of this time is to heat up the pipe ends.
After expiration of the heating time, the slides are opened, the heating element is removed quickly and
the pipes are driven together again. The time gap from the removal of the heating element to joining the
pipes is called change over time.
The pipes are joined under prescribed welding pressure and then cool down under pressure (cooling
time).
The welded joint can be un-clamped, the welding process is finished.
