A robot laser welding system consists of a servo-controlled, multi-axis mechanical arm, with a laser cutting head mounted to the faceplate of the robot arm.
The cutting head has focusing optics for the laser light and an integral height control mechanism. An assist gas delivery package distributes a gas, such as oxygen or nitrogen, to the welding head. Most systems use a laser generator that delivers the laser light to the robot cutting head through a fiber-optic cable.
An industrial robot can easily automate the laser welding process.
