Body Repairs with Adhesives and Welding
"Adhesion" is understood to be the joining of identical or
different materials by means of an inorganic or organic compound at
room temperature or with moderate heating. The practical
application of the adhesion method is limited to self-supporting
parts of the body, outer rear quarter panel. This application must
not be used for load-bearing parts, frames, members.
As of MY 1998 outer rear quarter panels shall be joined to the
rear wheel housing in the wheel cut-out area using putty adhesive
rather than spot welding.
The costs of repair and maintenance of a vehicle have a great
influence on its appeal to the customer and therefore contribute to
its competitiveness.
Therefore, it is obvious that cost development must be
constantly supervised, and that work methods that reduce costs be
developed.
The adhesion method developed by Opel and geared to the
requirements of body repair is the logical consequence of
developing and successfully applying to the automotive field modern
techniques that have proven useful and economical in other fields
of industry, such as aviation design.

The corrosion protection adhesive sealing system is available
from the Aftersales department as a set.
The new product replaces the familiar 2-component adhesive used
for replacement of exterior panelling (doors).
Apply adhesive with the Adhesive Pistol BETAGUN 2000.
This ensures 100% mixing of the two adhesive components.

General
In production plants the door outer panelling and the door inner
panelling as well as the outside and inside rear quarter panels in
the wheel housing area, fuel filler port and rear lamp insert are
assembled additionally with putty adhesive and reduced spot
welding. The remaining flanges will continue to be machined as
before.

Description of operations and applications:
- Observe occupational health and safety regulations (see Part
and Product Specifications)
- Detach attaching parts and rear quarter panel
- Remove residual adhesive from inside of rear quarter panel and
grind adhesive area down to bare metal
Note: Adhesive in the
area of separation points / edge welds must be protected from
combustion by applying heat barrier paste to the adjoining sheet
metal parts.
|
|
Note:
- Never apply weld paint on bright-finished adhesive
flanges.
- Only grind the adhesive surface of the new part flat in the
area of the weak points (also in the case of galvanised sheet metal
parts)
- Fit new part, observe cutting points
- Activate adhesive surfaces (new primed part) with activator
from adhesive kit. Insert adhesive cartridges from adhesive kit in
BETAGUN 2000; apply 10 cm test bead (e.g. on cardboard).
- Pre-cut cartridge nozzle (round nozzle) for 4 mm diameter.
- Quickly apply adhesive bead, install new part.
