body-in-white
assembly
The body shop is a large metal processing
industrial hall with a height of 6 to 9 meters.
The pressed components from the press shop are
welded together here. This process is partly fully
automated by robots, and partly semi-automated.
Fully automated welding lines are often illuminated
at higher levels than manual spot-welding locations.
Process control can only occur successfully if high
lighting levels are available. During the production
process, complete subassemblies (doors, side
panels, bonnets) are checked and inspected.
Finally, the complete body is carefully checked
for small press errors and welding drips.
Due to the dark appearance of the material
(grey and galvanized metal) and the dirty
environment (caused by welding), the body shop
gives a very dark impression.

Illuminance should be relatively high due to
poor luminance contrasts. Uniformity is heavily
influenced by ceiling-mounted obstructions,
and should be reasonably good. For inspection
of the body and its parts, direct glare should be
avoided, high illuminances are necessary and the
most comfortable light color (warm white)
should be installed.
Plastics applied in luminaires should be oil-
resistant. Self-cleaning luminaires should preferably
be used. At locations where welding smog is
continuously generated, luminaires should be
closed or screened off with an easy-to-clean opal
or prismatic cover. Where luminaires are applied
at ceiling heights of below 2 meters (during
inspection of vertical surfaces), impact-resistant
luminaires should be specified. A separate, fully
closed room is sometimes available for detailed
and random test checks. Good results are obtained
with warm white or green fluorescent lamps,
as these offer the best viewing conditions.
Typical lighting installation
Either wide-beam high-bay industrial luminaires
or white fluorescent reflectors can be employed.
An even light distribution offers the greatest
flexibility for future expansion of the factory.
For localized lighting required during inspection,
direct discomfort caused by glare from bare
lamps and lamps in white reflectors should be
prevented by the use of louvers.
