The plastic pipes are clamped by means of corresponding clamping tools.
Insert the plastic pipes and clamp them by means of the clamping tools.
Afterwards, the planer is driven into the machine and the front sides of the pipes are planed in parallel by
means of the planer, and the pipe displacement is checked. The planer is then driven back to its basic
position.
Then the heating element is driven inside and the pipes are pressed onto the heating element under the
defined pressure (this process is called: „adjustment time“).
After reaching the prescribed bead height the pressure is being reduced and this is the start of the heating
time.
The function of this time is to bring the pipe ends onto the welding temperature.
After completion of the heating time the machine is opened the heating element quickly driven out and the
pipes are again driven together hydraulically.
The time gap from driving out the heating element to the joining of the pipes is called change over time.
They are put together with the prescribed welding pressure and then cool down under pressure (cooling
time).
The welding connection can now be unclamped: the welding process is completed.
Heating element heats the pipes
up to welding temperature
