Joining tec hniq ues
I n order t o meet the high demand s with r e gard t o
body rigidity , cr a s h saf e ty and optimised pr oduction
pr ocesses, the f o llowing joining tec h niq u es a r e
emplo y ed on the A u di Q7:
– S p o t w e l d i ng
– S p o t w e l d b o nd i ng
– M A G w e l d i ng
– L a s er soldering
– P la smatr o n soldering
T h e joining tec h niq u e most fr eq uently emplo y ed f o r
ar ea s subject t o high load s is spot weld bonding
using a structur al adhesive.
T h e bonded jo ints, w i th a length o f 79815 mm,
co mprise 5403 spot welds. T h e t o tal length o f the
la ser - solder ed join ts ( s eamless joints betwee n r o of
and si d e fr ame) amou nts t o 4420 mm. As with the
A u di A3 Spo r tbac k and the A u di A6 Avant '05, the
side pa nel a nd the r a in c h a n nel ar e joined using
pla s matr on solde r ing. Like la ser soldering, this
te c h niq u e ensur e s a h i gh-q uality and a vir t ually
invisible seam. T h e length of the le f t and right joints
amo u nts t o 1438 mm. T h e length of the MA G
