REPLACEMENT OPERATIONS

• 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:0000000010479320

SPOT WELDING

The spot welding is limited to ultra high strength steel of tensile strength 980 MPa under the conditions listed
below.

CAUTION:

• If this condition is not satisfied, then perform plug welding.
• This condition is inapplicable to ultra high strength steel of tensile strength more than 980 MPa. For

this type of ultrahigh strength steel, perform plug welding.

• Since this condition is applicable only to this vehicle (J11), never apply it to welding conditions of

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 manual.

CAUTION:

• To perform plug welding, use fuel mixture (Ar 80% + CO2 20%) for shielding gas of welder.
• If carbon dioxide gas (CO2 100%) is used for shielding gas of welder, adequate weld strength cannot

be secured. For this reason, always use fuel mixture for shielding gas of welder to prevent.

• When welding hole diameter cannot be satisfied, make multiple holes (smaller diameter) so that the

sum of hole areas becomes equal to the area of the specified weld hole.
