    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. A is reused.

      Note

      Be careful when cutting as foamed sealing material is located near the cutting position.

    3. Roughly cut open the panel so that the adhesive can be reached. Cut through the adhesive with a cut chisel to remove the panel.

      Tech Tips

      In cases where the adhesive cannot be removed with a cut chisel, heat the adhesive with an industrial heater gun or gas burner taking care not to cause panel deformation by overheating.

    4. 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.

    5. Apply adhesive (3MTMAutomixTMPanel Bonding Adhesive #8115).

      Tech Tips


      • Apply a light coat of adhesive around the plug welding points.

      • Apply enough adhesive to the panels.

        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 1500 MPa ultra high strength steel.

        *a: 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.

    7. Apply adhesive (3MTMAutomixTMPanel Bonding Adhesive #8115).

      Tech Tips


      • Apply a light coat of adhesive around the plug welding points.

      • Apply enough adhesive to the panels.

        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 1500 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.

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

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