• When welding HSS panels, use spot welding whenever possi-

ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use MIG. welding. Do not use
gas (torch) for welding because it is inferior in welding
strength.

• Spot welding on HSS panels is harder than that of an ordinary

steel panel.
Therefore, when cutting spot welds on a HSS panel, use a low
speed high torque drill (1,000 to 1,200 rpm) to increase drill bit
durability and facilitate the operation.

2.

Precautions in spot welding HSS
This work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:
• The electrode tip diameter must be sized properly according to

the metal thickness.

• The panel surfaces must fit flush to each other, leaving no

gaps.

Foam Repair

INFOID:0000000010843492

During factory body assembly, foam insulators are installed in certain body panels and locations around the
vehicle. Use the following procedure(s) to replace any factory-installed foam insulators.

URETHANE FOAM APPLICATIONS

Use commercially available Urethane foam for sealant (foam material) repair of material used on vehicle.

Read instructions on product for fill procedures.

Example of foaming agent filling operation procedure

1.

Fill procedures after installation of service part.

a.

Eliminate foam material remaining on vehicle side.

b.

Clean area after eliminating form insulator and foam material.

c.

Install service part.

d.

Insert nozzle into hole near fill area and fill foam material or fill enough to close gap with the service part.

2.

Fill procedures before installation of service part.

a.

Eliminate foam material remaining on vehicle side.

b.

Clean area after eliminating foam insulator and foam material.
