ABSTRACT

A resistance spot welding device for vehicle assembly includes a welding gun
having an upper electrode and a lower electrode mounted thereon, the upper
electrode and the lower electrode facing each other, an adjustment jig for
adjusting straightness between the upper electrode and the lower electrode, an
image capturing apparatus mounted on the welding gun for photographing a
welding surface, teaching blocks respectively mounted on a plurality of
welding points formed on the welding surface, and a controller for
calculating, through image information on each of the teaching blocks received
from the image capturing apparatus, a rotation amount and a movement amount of
the welding gun, and to perform a control operation to correct a welding
position of the welding gun based on the calculated rotation amount and
movement amount.
