3–2 WELDING AND TOOLS

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 reli-
able results.

1-2. WELDING CONDITIONS

When performing spot welding, make absolutely sure
that you conform to the conditions governed by the
current, conductivity time, welding pressure, holding
time, and shutdown time recommended for the spot
welder.
Please bear in mind the following points when welding:
• 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.
