    1. Do not butt weld or heat repair because the heat decreases the strength of areas where ultra high strength steel is used. (See the introduction)

    2. Reuse A, as the area of the outer panel that is cut and joined is above the supplied part cut position.

    3. When replace only the outer panel, please cut off a necessary range depending on a damage range.


      1. Carefully cut the outer panel so not to damage the reinforcement.

      2. Make sure that butt welding does not heat-affect the reinforcement when welding the outer panel.

    1. Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the finish.

    2. Temporarily install the new parts and measure each part of the new parts in accordance with the body dimension diagram. (See the body dimensions)

    3. If the entire supply part is not needed, remove the part of the supply part that is needed.

      Tech Tips


      • Carefully cut the center body pillar reinforcement sub-assembly so not to damage A.

      • Carefully cut the No.4 inner pillar sub-assembly so not to damage B.

    4. Before temporarily installing the new parts, weld the center body pillar reinforcement sub-assembly and No.4 inner pillar sub-assembly with the standard number of welding points.

        Follow the welding conditions below when welding ultra high strength steel to assure sufficient weld strength. (When repairing this model)

      • When welding 2 panels together including 980 MPa ultra high strength steel.

        *a: Spot weld Pressure 2940 N (300 kgf, 661 lbf)
        Weld current 10000 A
        Weld time 18 Cyc. (0.30 Sec.)
        *b: Plug weld Plug diameter 10 mm (0.39 in.)
        Wire type AWS A5.18 ER70S-3
        Shield gas Metal active gas

        Note

        Be sure to use Metal active gas (Ar 80% + CO220%) as the shield gas when plug welding.Sufficient weld strength cannot be assured when using 100% CO2shield gas.

    5. Weld the center body pillar reinforcement sub-assembly and No.4 inner pillar sub-assembly to the vehicle side.

        Follow the welding conditions below when welding ultra high strength steel to assure sufficient weld strength. (When repairing this model)

      • When welding more than 3 panels together including 980 MPa ultra high strength steel. (When plug welding a third panel to 2 panels which are welded under the conditions described above.)

        *a: Plug weld Plug diameter Same as the standard method (See the introduction)
        Wire type AWS A5.18 ER70S-3
        Shield gas Metal active gas

        Note

        Be sure to use Metal active gas (Ar 80% + CO220%) as the shield gas when plug welding.Sufficient weld strength cannot be assured when using 100% CO2shield gas.

    7. After welding, apply the foamed sealing material to the corresponding parts. (See the painting/coating)

    8. After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
