CENTER BODY PILLAR CUT AND JOIN REPLACEMENT SECTIONS

Weld work for 1500 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 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: When welding more than 3 panels together including 1500 MPa ultra high strength steel. (When plug welding 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.

REMOVAL

Symbol meaning
	Remove Weld Points
	Remove Weld Points
	Cut with Disc Sander etc.
	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)
Reuse *3, as the area of the outer panel that is cut and joined is above the supplied part cut position.
*4 in illustration above indicates where the adhesive is located.
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.
Carefully cut the center body pillar reinforcement sub-assembly so not to damage *5.
*6 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
	Remove Weld Points
	Plug Weld
	Plug Weld
	Cut with Disc Sander etc.
	Cut and Join Location
	Butt Weld
	Body Sealer

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 dimensions)
If the entire supply part is not needed, remove the part of the supply part that is needed.
Carefully cut the center body pillar reinforcement sub-assembly so not to damage *3.
Carefully cut the center body pillar sub-assembly inner so not to damage *4.
Follow the welding conditions when welding *1 and *2 to assure sufficient weld strength. (See the introduction)
Apply adhesive (3M^TMAutomix^TMPanel Bonding Adhesive #8115) to the area indicated by *5 in the illustration.
Tech Tips
- Apply a light coat of adhesive around the plug welding points.
- Apply enough adhesive to the panels.
Before temporarily installing the new parts, weld the center body pillar reinforcement sub-assembly and center body pillar sub-assembly inner with the standard number of welding points.
After welding the center body pillar reinforcement sub-assembly and center body pillar sub-assembly inner to the vehicle side, install the center body pillar outer and *6.
*7 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.
After welding, apply the foamed sealing material to the corresponding parts. (See the painting / coating)
After applying the top coat, apply anti-rust agent to the internal panel portion of the closed section structural weld points.
