A robot laser welding system consists of a servo-controlled, multi-axis mechanical arm, with a laser cutting head mounted to the face plate 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.
A Robot Laser Welding Machine can easily automate this application and manufacturers will see improved repeatability and higher quality welds.

The benefits of Robot Laser Welding Machine:
As mentioned, robotic laser welding is inherently precise. Laser welding beams create deep and accurate welds without using nearly as much energy or resources as traditional welding processes. Since laser welds are so precise and focused, welds are cleaner and require far less touch-up or rework.
Laser welding solutions are also more versatile. Traditional welding methods will always excel at applications where there is a gap between welding parts, but other applications that would benefit from high accuracy and speed will be better off with laser welding. Robotic laser welding has a much smaller heat-affected zone, so distortion is minimized regardless of the type of metal being welding.
Robotic laser welding is an accurate, clean and flexible option for a wide variety of welding applications. While it will never be a replacement for traditional welding processes, it still has many benefits and any manufacturer looking to automate welding processes should at least consider a robotic laser welding solution.
