CENTER BODY PILLAR CUT AND JOIN REPLACEMENT SECTIONS

A0025CR

    Weld work for 1500 MPa ultra high strength steel Follow the welding conditions below when welding ultra high strength steel to assure sufficientweld strength. (When repairing this model)

  1. *a: When welding 2 panels together including 1500 MPa ultra high strength steel.

    Plug weld Plug diameter 10 mm (0.39 in.)
    Wire type AWS A5.18 ER70S-3
    Shield gas Metal active gas

  2. *b: When welding more than 3 panels together including 1500 MPa ultra high strength steel. (When plugwelding a third panel to 2 panels which are welded under the conditions described above.)

    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.

    A002561 Cut Location for Supply Parts

      REMOVAL POINT

    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. *c in the illustration indicates the laser screw welding location.

    3. A is reused.

    4. *d in illustration indicates where the adhesive is located.

    5. 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.

    6. B indicates the location of the foamed sealing material. Be careful when cutting as the foamed sealing material is located near the cutting position.

      INSTALLATION POINT

    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. *c in the illustration indicates the laser screw welding location.

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

    5. Follow the welding conditions when welding *a and *b to assure sufficient weld strength. (See the introduction)

    6. Apply adhesive (3MTMAutomixTMPanel Bonding Adhesive #8115) to the area indicated by *d in the illustration.

      Tech Tips


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

      • Apply enough adhesive to the panels.

    7. A indicates the location of the foamed sealing material. Be careful when welding as the foamed sealing material is located near the area that is cut and joined together.

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

    9. After welding the center body pillar sub-assembly inner and center body pillar reinforcement sub-assembly to the vehicle side, install the center body pillar outer and B.

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

    11. After welding, apply body sealer to the corresponding parts. (See the painting / coating)

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