  1. Weld work for 980 MPa ultra high strength steel
Follow the welding conditions below when welding ultra high strength steel to assure sufficient weld strength. (When repairing this model)
  1. *1: When welding 2 panels together including 980 MPa ultra high strength steel.

    Spot weld
    Pressure
    2940 N (300 kgf, 661 lbf)
    Weld current
    10000 A
    Weld time
    16 Cyc. (0.27 Sec.)
    Plug weld
    Plug diameter
    10 mm (0.39 in.)
    Wire type
    AWS A5.18 ER70S-3
    Shield gas
    Metal active gas
  1. *2: When welding more than 3 panels together including 980 MPa ultra high strength steel. (When plug welding a panel to the welded panels with the weld condition 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

NOTICE:
Be sure to use Metal active gas (Ar 80% + CO2 20%) as the shield gas when plug welding. Sufficient weld strength cannot be assured when using 100% CO2 shield gas.

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. *3 is reused.
  3. *4 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 dimension diagram)
  3. Follow the welding conditions when welding *1 and *2 to assure sufficient weld strength. (See the introduction)
  4. Before temporarily installing the new parts, weld the center body pillar lower reinforce and center body pillar reinforcement with the standard number of welding points.
  5. After welding the center body pillar lower reinforce and center body pillar reinforcement to the vehicle side, install the center body outer pillar and *3.
  6. After welding, apply the foamed sealing material to the corresponding parts. (See the paint / coating)
  7. After welding, apply body sealer to the corresponding parts. (See the paint / coating)
  8. After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
