• The spot weld on HSS panels is harder than that of an ordi-
nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a low
speed high torque drill (1,000 to 1,200 rpm) to increase drill bit
durability and facilitate the operation.
2. Precautions in spot welding HSS
This work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:
• The electrode tip diameter must be sized properly according to
the metal thickness.
• The panel surfaces must fit flush to each other, leaving no
gaps.
• Follow the specifications for the proper welding pitch.

• Apply new adhesive to both specified areas of outer wheelhouse
and rear fender.
• Attach rear fender to the body of the car, and weld the required
part except the hemming part.
• Bend the welded part starting from the center of the wheel arch
gradually with a hammer and a dolly. (Also hem the end of the
flange.)
• Hemming with a hammer is conducted to an approximate angle of
80 degrees.
• Starting from the center, hem the wheel arch gradually, using slight
back and forth motion with a hemming tool.
• Seal up the area around the hemmed end of the flange.

• 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. Refer to the front
pillar section.
• 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 above inner front pillar cut position.
• Prepare a cutting jig to make outer pillar easier to cut. Also, this will
permit service part to be accurately cut at joint position.
• An example of cutting operation using a cutting jig is as follows.
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.
