Land Rover Discovery: Partial Renewal
The procedure to follow when partially renewing components is the same as
described in the section "Welded Components".
The main difference when components are partially, rather than completely
renewed, concerns the preparation of butt or lap joints.
- When bodywork components are cut through, attention must be paid to
the adequate removal of the paint and zinc coatings on inner areas. This
specially applies to areas which are difficult to access internally.
- It is important for the weld quality that the inner area is bare metal.
Zinc
and paint residues in the weld area burn and cause serious hole formation
during welding.
- If the zinc layer and the paint coating are not removed, the zinc and
paint
will burn during welding. The soot produced prevents satisfactory cavity
protection.
Procedure
- The paint layer must be removed for a width of 30 mm from the line of
the weld using a rotating tress wire brush.
- This operation must be carried out on both the new and the old parts of
the bodywork.
- Depending on the bodywork component, a 10 mm width of the
underlying zinc layer must also be removed along the weld line.
NOTE:
A flat scraper or a wire brush can be used instead of the rotating
brush if the cavity is small. Do not use an angle grinder, which would
reduce panel integrity and may weaken the structure.
