DESCRIPTION AND OPERATION
Readily flammable overalls or gloves must not be
Electro — Coat
worn during welding operations. In addition, fuel
lines, tank and any other flammable materials
All panels supplied are E-coated in the plant. This is
including wiring looms must be removed if welding
an anti-corrosion paint, not a surface primer. All
is to be carried out in the vicinity.
panels must be lightly scuffed and painted with a two
pack primer or primer filler (to improve appearance
When carrying out welding and similar operations,
and to prevent top coat peeling) and then receive
overalls etc., made of Nylon, Perion, Dralon, etc.,
normal treatment up to finish coat.
must not be worn.
Fitting new panels require the removal of E-coat
where welding is required and the use of a
weld-through zinc rich primer.
Corrosion Prevention
Vehicles requiring body repair must have the
anti-corrosion protection reinstated during the repair.
The level of protection required and the
recommended materials are contained in the following
pages.
Care should be taken when substituting other type
materials, that they will not cause a long term
problem, e.g,. Acid curing silicons will promote
corrosion when used in contact with painted or bare
metal panels.
Corrosion Protection
Safety Precautions
Anti-corrosion treatments, waxing agents and plastics
used in vehicles produce vapours when heated which
may cause serious injury if inhaled.
In addition to the normal requirements for a safe work
place, ensure the following precautions are observed:
Keep a fire extinguisher within reach. This safety
precaution must be taken although the
anti-corrosion treatments generally do not
constitute a direct fire risk.
Remove anti-corrosion treatments as far as
possible from the vicinity of the area to be welded.
Polyurethane hard foam can be removed with
cutting tools, wax and underseal are preferably
removed using sanding discs or , wire brushes.
Wax and underseal can also be removed usinf a
hot-air-blower of the kind employed by decorators
when laying plastic floors.
If anti-corrosion treatments cannot be removed
due to lack of space or inaccessibility, fumes and
gases produced during welding operations must
be extracted directly. This is best accomplished
with special extractors with suction heads on
flexible hoses that can be conveniently positioned
in the working area.
Welding operations should always be carried out
in seperate, well ventilated areas. Breathing
masks must always be used.
A hole should be drilled in cavities filled with hard
foam on the side away from the operator so that
vapours can escape.
