What is the payload capacity of an industrial robot?

The payload capacity of an industrial robot refers to the maximum weight the robot arm can safely handle, including the end-effector (such as a gripper or welding torch) and the workpiece. 

Payload capacity varies by robot model and is a key factor when selecting the right robot for a specific application.

Choosing the right payload requires evaluating several factors, including the weight of the workpiece, the tooling or gripper, additional accessories, and a safety margin. An accurate calculation ensures stable motion, long-term reliability, and optimal performance.

For most robotic welding applications, robots with payloads between 6 kg and 20 kg are commonly used. The exact requirement depends on the welding torch, cable system, and additional peripherals. Heavy-duty welding or large workpieces may require higher-capacity robots.

Yes. Operating a robot close to its maximum payload may reduce speed, accuracy, and service life. Selecting a robot with an appropriate payload margin ensures smoother motion, better repeatability, and more reliable long-term operation.

RBTC evaluates actual production conditions, including part weight, process requirements, tooling configuration, and cycle time. Based on this analysis, we recommend suitable industrial robot models and system designs to ensure safe, efficient, and stable automation performance.
