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: 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
|
- *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
- 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)
- *3 is reused.
- *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
- Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the finish.
- 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)
- Follow the welding conditions when welding *1 and *2 to assure sufficient weld strength. (See the introduction)
- 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.
- 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.
- After welding, apply the foamed sealing material to the corresponding parts. (See the paint / coating)
- After welding, apply body sealer to the corresponding parts. (See the paint / coating)
- After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
