3–2 WELDING AND TOOLSNUBIRA/LACETTI
1. SPOT WELDING
1–1. GENERAL DESCRIPTION
.
Spot welding is also known as resistance spot welding
and it is the most suitable method of welding for auto-
mobiles. It has three main features: the welding can be
performed instantaneously, it exercises very little effect
on the mother material, and it reduces the generation of
distortion to the absolute minimum. However, please
remember to remove all paint and other impurities from
the surface of the material you intend to weld for reliable
results.
.
1–2. WELDING CONDITIONS
.
When performing spot welding, make absolutely sure
that you conform to the conditions governed by the cur-
rent, conductivity time, welding pressure, holding time,
and shutdown time recommended for the spot welder.
Please bear in mind the following points when welding :
.
S Plate thickness and minimum welding pitch
Note : When the welding intervals are too small, this leads
to branching, making it impossible to maintain the desired
soldering state.

2. FRONT WHEELHOUSE
2–1. GENERAL DESCRIPTION
The front wheelhouse component is constructed as a
unit with the locator shockabsorber. Therefore, replace-
ment of the component affects the front wheel align-ment. When assembling it, either use a jig or follow di-
mensions on the body repair chart for positioning. It
must be welded carefully.
