The plastic pipes are clamped in 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 cleaned and heated 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 unclamped, the welding process is finished.
Heating element heats the pipes
up to welding temperature
