| 摘要 |
The invention relates to a method for connecting a first plastic part (2, 2') to a second plastic part (4) by laser welding, wherein the two plastic parts (2, 2', 4) are positioned on one another, pressed together in a clamping device by a transparent holding-down element (11) and bonded to one another by laser welding with a laser light (7). The invention is distinguished by the fact that the two plastic parts (2, 2', 4) are made transparent to laser light (7), that at least the second plastic part (4) is made thin, that, for the welding, the second plastic part (4) has placed in front of it, on the outer side (16) that is facing away from the first plastic part (2), a mat (8) that absorbs the laser light (7), cannot be melted by the laser light (7) and does not become connected to the second plastic part (4) in contact with it, and that the laser light (7) is fed to the second plastic part (4) via the first plastic part (2). |
