PRECAUTIONS IN REPAIRING HIGH STRENGTH STEEL

• When cutting HSS panels, avoid gas (torch) cutting if possible.

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).

• 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.

• The spot weld on HSS panels is harder than that of an ordi-

nary 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

Description

INFOID:0000000009465846

This section is prepared for technicians who have attained a high level of skill and experience in repairing col-

lision-damaged vehicles and also use modern service tools and equipment. Persons unfamiliar with body

repair techniques should not attempt to repair collision-damaged vehicles by using this section.

Technicians are also encouraged to read Body Repair Manual (Fundamentals) in order to ensure that the orig-

inal functions and quality of the vehicle can be maintained. The Body Repair Manual (Fundamentals) contains

additional information, including cautions and warnings, that are not including in this manual. Technicians

should refer to both manuals to ensure proper repairs.

Please note that this information is prepared for worldwide usage, and as such, certain procedures might not
