ABSTRACT:
A device for welding a plurality of thermoplastic plastic parts (parts to be joined) forming a hollow body with an opening by a laser, comprising a vacuum holder having a vacuum chamber which communicates with a vacuum pump, is open on one side and, together with the hollow body, forms a closed chamber that can be evacuated. When a vacuum is applied, the vacuum holder holds the hollow body stationary, holds the joined parts together and enables testing of the tightness of the weld.
