    2. 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.

    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. After welding the center body pillar sub-assembly inner to the vehicle side, install the A.

      *a Ultra High Strength Steel Welding Point - -

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

      • When welding 2 panels together including 780 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.

    4. 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.
