Joining technique
Various joining techniques
are applied to interconnect the individual body
elements.
Spot welding joining
Crash-relevant and
rigidity-defining
joints are spot-weld bonded using a high-strength
structural adhesive.
The overall length of the bonded seams is approx.
26 m.
Laser welding
Laser welding is used in areas which are not easily
accessible.
The total length of the laser welded joints is approx.
25 m.
Laser soldering
Laser-solder joining is used to achieve a better
design and higher rigidity in the area of the
invisible joint and boot lid.
The total length of the laser-soldered joints is
approx. 3.3 m
Plasma soldering
To ensure the high rigidity and good design of the
water channel,
materials are joined by plasma soldering.
The overall length of the plasma-soldered joints is
approx. 1.1 m.
