Read the following precautions when repairing HSS and UHSS:

Following precautions

  1. Additional points to consider

    • The repair of reinforcements (such as side members) by heating is not recommended, because it may weaken the component. When heating is unavoidable, never heat HSS parts above 550°C (1,022°F).

      Verify heating temperature with a thermometer.

      (Crayon-type and other similar type thermometer are appropriate.)

      When you heat the HSS or UHSS parts above 550°C (1,022°F), it must be replaced with new parts.

    • When straightening body panels, use caution in pulling any HSS panel. Because HSS is very strong, pulling may cause deformation in adjacent sections of the body. In this case, increase the number of measuring points, and carefully pull the HSS panel.

    • 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 possible 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 conditions. 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.

    • Follow the specifications for the proper welding pitch.

      Unit: mm (in)

      Thickness (T) Minimum pitch (L)

      0.6 (0.024)

      0.8 (0.031)

      1.0 (0.039)

      1.2 (0.047)

      1.6 (0.063)

      1.8 (0.071)

      10 (0.39) or more

      12 (0.47) or more

      18 (0.71) or more

      20 (0.79) or more

      27 (1.06) or more

      31 (1.22) or more

Painting Booth

Temperature Control

While using painting booth, outer sill temperature must not exceed 60°C (140°F) to prevent deterioration of li-ion battery.

NOTE:

If outer sill temperature becomes more than 60°C (140°F), paint booth must be shut off immediately.

Protection of Vehicle

Protection of Vehicle

The seats, glass, and carpet must be removed or covered with appropriate material (spatter cover), according to the type of work to be done, to prevent contamination and welding spatter.

In addition, when cutting the vehicle in an area close to high voltage parts or performing a welding operation, the high voltage parts must be covered with a heat-resistant insulating cover (spatter cover).
