Beschreibung
Zusammenfassung:	A device for assembling a first upper transparent part to a second lower absorbent part, the parts being positioned on a support. The device includes a mechanism projecting a laser beam onto the upper part, a first clamp geometrically referencing the assembly formed by the two parts and positioned on the support, a second clamp exerting a pre-determined stress on the assembly of parts, and a management system associated with the second clamp, adjusting the stress exerted at a pre-determined welding interface. An assembly method is intended for laser-transparent welding of two parts assembled using one such assembly device. The clamping fitting is configured to apply the stress exerted at the welding interface.
