WELDING
BASE OF BODY REPAIR 9-6
WELDING REQUIREMENTS
Standard steel plate (SPCC, etc.)
CAUTION
If the total thickness of the plates at the weld
places is 3 mm (0.12 inch) or more, use plug
welding, because spot welding will not provide
sufficient welded strength.
Example
•
Center pillar (outer): plate thickness 1.4 mm (0.06
inch), material SPCC
•
Center pillar (inner): plate thickness 1.5 mm (0.06
inch), material SPCC
The number of weld points are as below when the
outer and inner center pillars are repaired by weld-
ing.
*: For welding steel plates of different thickness, con-
form to the welding conditions for the thinner plate.

11 POINTS 11 POINTS
REPAIR WELDS (R)
As shown by the Welding Requirements table, the number of repair welds is as follows.
8 (points)
×
130 (%) = 10.4 (points)
The number of weld points should, therefore, be ten or eleven.
If, however, a pitch of 26 mm (1.0 inch) or more cannot be maintained, the plug
welding method (eight weld points) should be used.
