Parameters of Robotic Laser Systems
Matching Welding Speed with Quality: The choice of welding speed must be coordinated with welding quality. Excessive welding speed may lead to welding defects such as deviation, insufficient welding, and leakage. Conversely, too slow welding speed can affect product production efficiency. Therefore, welding speed, as a key indicator determining welding efficiency, needs to be fine-tuned while ensuring quality.
Rated Load of Robot Arm: This metric refers to the load that the end of a robot laser welding machine can bear. The rated load on the wrist directly affects its arm reach and the specifications of welded components, including the welding gun, cables, visual sensors, wire feeding tubes, and more. This consideration is crucial for ensuring the robot’s robust operation and adaptability to different welding conditions.
Axis and Flexibility: The number of axes affects the flexibility of the robot laser welding machine. The more axes it has, the more flexible the robot is, capable of handling a wider range of welded part specifications, expanding the scope of welding applications.
Arm Reach and Welding Radius: The arm reach of the robot laser welding machine reflects its welding radius. A longer arm reach corresponds to a larger welding radius, allowing the robot to handle larger welded part specifications. Users can choose the appropriate arm reach based on welding space, part specifications, and welding requirements.
Robot Weight: The weight of the robot laser welding machine varies with specifications. Weight is closely related to arm reach and welding range. Selecting a robot with the appropriate weight helps ensure its stability and reliability during operation.
Repeat Positioning Accuracy: The welding accuracy that the robot laser welding machine maintains during repetitive actions. Only a robot laser welding machine with high repeat positioning accuracy can ensure welding precision without deviation. Balancing welding quality and positioning accuracy is crucial while pursuing efficiency.
Movement Speed: The movement speed of the robot laser welding machine is a key indicator, requiring it to complete multiple small-distance multi-point positioning in a short time. To guarantee welding quality, it also needs to maintain high positioning accuracy (typically 0.25mm) and sufficient load capacity to adapt to variable welding conditions.
