The plastic pipes are clamped by means of the clamping tools.
Then the front of the pipes are planed. As soon as the pipes are parallel and the pipe deviation is
smaller than 0,1x pipe thickness, the welding can begin.
Now the clamping tool with the pipes must be moved forward against the heating element until a
certain pressure is achieved. Now the pipes are heated up and a circular bead arises.
This happens during the bead-up time bead-up time bead-up time bead-up time.
After reaching the necessary bead-height, the pressure is reduced, and this is the beginning of the
heat-up time
heat-up time heat-up time heat-up time, this time is used to heat-up the pipe ends.
After heat-up time the support must be moved backward and the heating element must be removed as
quickly as possible and the pipes driven together again.
The time between moving backward of the support and moving forward again after the heating
element is taken out ist called change-over time
change-over time change-over time change-over time.
The pipes are fitted together according to the prescribed welding pressure and now the pipe cools
down under pressure (cool-down time
cool-down time cool-down time cool-down time).
The welded pipes can be unclamped, the welding process is finished
