Abstract
In the method of bonding two parts (1,2) together a positioning device (3) accurately positions the two parts (1,2) relative to each other and a comparatively slower hardening adhesive layer (4) is applied between the two parts (1,2) to bond the two parts (1,2) together. After the adhesive layer (4) is applied and the parts positioned, a faster hardening UV adhesive (5) is applied on adjacent edge regions of the two parts (1,2) over an edge of the slower hardening adhesive layer (4), so that the faster hardening UV adhesive (5) is accessible for UV irradiation. Subsequently the faster hardening UV adhesive (5) is hardened with the UV radiation and the positioning device (3) is removed from the parts (1,2) which are held fixed in a provisional manner. Then the slower hardening adhesive layer (4) is hardened preferably in an oven that can be used for a large number of similar pairs of parts.
