Among the welding technologies, spot welding technology which has a close relationship with automation.

-	A representative example of automated spot welding technology is the automotive production lines.
-	Automobile production line is composed of a collection of about 300 process steps, and about 4000 parts are assembled in around 50 seconds cycle time.
-	The representative technology that realizes the high production efficiency, high quality, weight reduction, body strength improvements, and safety is the spot welding technology.
-	The dedicated devices that perform high speed spot welding processes are the units with integrated high level technology with names such as Servo Guns and Air Guns.
