• Front pillar butt joint can be determined anywhere within shaded
area as shown in the figure. The best location for the butt joint is at
position A due to the construction of the vehicle.
• Determine cutting position and record distance from the locating
indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm (2.36 in) above the inner front pillar cut
position.
• Prepare a cutting jig to make outer pillar easier to cut. Also, this will
permit the service part to be accurately cut at the joint position.
• An example of cutting operation using a cutting jig is as per the fol-
lowing.
1.
Mark cutting lines.
A: Cut position of outer pillar
B: Cut position of inner pillar
2.
Align cutting line with notch on jig. Clamp jig to pillar.
3.
Cut outer pillar along groove of jig (at position A).
4.
Remove jig and cut remaining portions.
5.
Cut inner pillar at position B in same manner.
Welding of Ultra High Strength Steel
INFOID:0000000010843609
SPOT WELDING
Spot welding is limited to ultra high strength steel (tensile strength: 980 MPa) according to the welding condi-
tions listed below.
CAUTION:
• If the below welding conditions cannot be met, then perform plug welding.
• Never spot weld ultra high strength steel of tensile strength more than 980 MPa. For this type of ultra
high strength steel, perform plug welding.

• The below welding condition is applicable only to this vehicle. Never apply this same welding condi-
tion to other vehicles.
Welding condition
PLUG WELDING
To weld ultra high strength steel of tensile strength 980 MPa or more, perform plug welding observing the
welding hole diameter described in the instruction.
CAUTION:
• To perform plug welding, use fuel mixture (Ar 80% + CO2 20%) for shielding gas of welder.
• Never use carbon dioxide gas (CO2 100%) as shielding gas of welder. Using CO2 100% gas results in
inadequate weld strength.
• When welding hole diameter cannot be met, make multiple holes (smaller diameter) so that the sum
of the hole areas equals the area of the original weld hole.
