Due to the high rigidity there is a risk that
cracks will form.
The bonding techniques that are used are
MIG welding, riveting and adhesive bonding.
The general repair process is demonstrated
on the B-pillar.
Extruded profile parts must be replaced if
they are damaged. Any reshaping would be
uncontrollable.
Depending on the type of damage, parts can
be replaced either by section using socket
welds in the join area (see Page 59) or as a
complete unit.
The replaced profiles and sections are joined
by MIG welding.
As a general rule, damaged cast parts
must always be replaced.
For strength reasons reshaping is not
permitted.
