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

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.

REMOVAL

Symbol meaning
	Remove Weld Points
	Cut and Join Location
	Cut Location for Supply Parts

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

Symbol meaning
	Spot Weld
	Plug Weld
	Cut and Join Location
	Butt Weld

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.
