The weldment is pressed between two columnar electrodes and heated
by electricity, so that the weldment melts at the contact and forms
a nugget. Then power off, the weldment is solidified and
crystallized under pressure to form a dense welding spot. This is
the principle of spot welding. Spot welding is suitable for welding
thin plate (lap) and steel bar. It is widely used in the production
of automobile, aircraft, electronics, instruments and daily
necessities.
