所述盖（1）具有表示管件斜槽通道（2），和一个凸缘（3）在管片的一端形成并且向外突出到所述管件的外周表面。 凸缘的自由前侧通过焊接连接与盖连接，并且焊接突节（4）在凸缘的前侧海誓山盟的距离而形成。 突节表示与盖焊接过的金块区域中的焊接连接，并有高度差海誓山盟。 凸缘的公差变化对应于respectivement突节的位置。 因此独立权利要求中包括了以下内容：用于与斜槽通道（2）在安全气囊罩用斜槽道制造方法安全气囊罩的焊接（1）的装置。

The invention relates to an airbag cover with deployment channel, wherein the airbag cover (1) and the shot sleeve (2) are neutral interconnected by a welded joint. For the production of the weld (2) welding studs (4) on a flange (3) of the firing channel is formed, at a height greater than the tolerance width (+/- a) of the flange (3), and during the welding of the weft passage (2) to a displacement distance greater the tolerance range (+/- a) and less of the height (h) of the welding studs (4) on the airbag cover (1) to move. The welding of the welding studs (4) with the airbag cover (1) being carried out simultaneously by using a laser beam of radiation is directed onto each Schweißnoppe, wherein the cross sections of the laser radiation beam and the welding studs (4) are matched to one another.
