Preparation time of jointing pressure

The preparation time of jointing pressure is the time during which the join partners are welded after the plasticising process. At that time, when the join partners come into contact, the welding speed is near zero. The welding pressure is gradually increased within the specified preparation time of jointing pressure according to DVS 2207-1 until it reaches the welding pressure that is also stipulated in DVS 2207-1. It is in this phase that the quality of the welding seam is largely determined.
