High Strength Steel (HSS)
High strength steel is used for body panels in order to reduce vehicle weight.
Accordingly, precautions in repairing automotive bodies made of high strength steel are described below:
Read the following precautions when repairing HSS:
When heating is unavoidable, do not heat HSS parts above 550C (1,022F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropriate.)
Instead, use a saw to avoid weakening surrounding areas due to heat. If gas (torch) cutting is unavoidable, allow a minimum margin of 50 mm (1.97 in).
If spot welding is impossible, use MIG. welding. Do not use gas (torch) for welding because it is inferior in welding strength.
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.
Always note the following when spot welding HSS:

Towing a trailer
Flat towing
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
Failure to follow these guidelines can
result in severe transmission damage ...
