• This section contains information on the body panels in regard to the welding types, number of spot welds, and
cut-and-join locations that are necessary for panel removal and installation.
• The type of weld and position are indicated by symbols.
• Some sections have notes concerning the operation being performed. Thoroughly read and understand the
notes before carrying out any procedures.

• Flat-plane dimensions are the dimensions measured by projecting certain reference points onto a plane
surface.
• When there are no specific indications, the standard points and dimensions are symmetrical in regard to the
center of the vehicle.
• The hypothetical lines may differ according to the vehicle model.

Symbols of Body Dimensions
• The following 8 symbols are used to indicate the standard points.
• Arrangement of the workshop is important for safe and efficient work.
Safety Precautions
• Protective head covering and safety shoes should
always be worn. Depending upon the nature of
the work, gloves, safety glasses, ear protectors,
face shield, etc., should also be used.

• Use heat-resistant protective covers to protect glass areas and seats from heat or sparks during welding.
• Protect items such as moldings, garnishes, and
ornaments with tape when welding.

Remove Dangerous Articles
• Remove the fuel tank before using an open flame
in that area. Plug connection piping to prevent
fuel leakage.
Use of Pulling Equipment
• When using pulling equipment, keep away from
the pulling area and use safety wires to prevent
accidents.

Prevent Short Circuits
• Turn the ignition switch to the LOCK position.
• Disconnect the battery cables.
• Securely connect the welding machine ground
near the welding area.

EFFICIENT REMOVAL OF BODY PANELS
Body Measurements
• Before removal or rough-cutting, first measure the
body at and around the damaged area against
the standard reference dimension specifications.
If there is deformation, use frame repair
equipment to make a rough correction.
Prevention of Body Deformation
• Use a clamp or a jack for removal and reinforce at
and around the rough-cutting location to prevent
deforming of the body.

GENERAL INFORMATION
Selection of Cut-and-join Locations
• For parts where complete replacement is not
feasible, careful cutting and joining operations
should be followed. If the location to be cut is a
flat area where there is no reinforcement, the
selected cutting location should be where the
welding distortion will be minimal.
MZJ2038B003
Removal of Associated Parts
• Protect moldings, garnishes, and ornaments with tape when removing associated parts.
Rough Cutting of Damaged Panel
• Verify that there are no parts (such as pipes, hoses, and wiring harness) nearby or on the opposite side of a
panel which could be damaged by heat.
• For cut-and-join areas, allow for an overlap of
30—50 mm {1.18—1.97 in} and then rough-cut
the damaged panel.

Welding Notes
• For the number of weld points, welding should be
performed in accordance with the following
reference standards.
Spot Welding Notes
• The shape of the spot welder tip is D=(2×t)+3. If
the upper panel thickness is different from that of
the under panel, adjust to the thinner one.

• Because the weld strength is affected by the
shape of the spot welder tip, the optimum
condition of the tip should always be maintained.
• Spot welds should be made at points other than
the originally welded points.
• Before spot welding, make a trial weld using the
same material as the body panel to check the
weld strength.

GENERAL INFORMATION
Checking Weld Strength
• Installation locations of the engine, chassis, and
seat belts are designated as important safety
locations for weld strength. Check weld strength
by driving a chisel between the panels at every
fourth or fifth weld spot, and every tenth regular
weld location.
• Drive the chisel between the panels according to
the number of panels as shown below.
• To determine weld strength, drive the chisel
between the panel and check whether the panels
come apart. If the panels come apart, make
another weld near the original weld.
• Restore the shape of the checked area.
