# ROCKER PANEL > CUT AND JOIN REPLACEMENT SECTIONS

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

Symbol meaning
| Remove Weld Points
| Remove Weld Points
| Remove Weld Points
| Cut with Disc Sander etc.
| Cut and Join Location
| 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)

INSTALLATION

Symbol meaning
| Remove Weld Points
| Plug Weld
| Plug Weld
| Plug Weld
| Cut and Join Location
| Fillet Weld
| Butt Weld
| Body Sealer

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. If the entire supply part is not needed, remove the part of the supply part that is needed.
4. Before installing a new part, apply body sealer.

   HINT:
     Apply body sealer in an even, continuous bead.
5. Follow the welding conditions when welding *1 and *2 to assure sufficient weld strength. (See the introduction)
6. Before temporarily installing the new parts, weld the rocker outer reinforce, center body pillar lower reinforce and center body pillar reinforcement with the standard number of welding points.
7. After welding the rocker outer reinforce, center body pillar lower reinforce and center body pillar reinforcement to the vehicle side, install the front body upper outer pillar and center body outer pillar.
8. After welding, apply body sealer and undercoating to the corresponding parts. (See the paint / coating)
9. After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
