2. Cartesian Welding Robots
Cartesian robots operate on a three-axis system, moving in straight lines along the X, Y, and Z axes. They are often used in tasks that require high-speed welding with simpler movements, such as in flat surfaces or specific angles.
3. Collaborative Welding Robots (Cobots)
Cobots are designed to work alongside human workers. These robots are equipped with sensors and safety systems to ensure safe collaboration, making them perfect for applications where human oversight or intervention is required.
How Welding Robots Work: Step-by-Step Process
Understanding the welding robot’s process can help you optimize its use in your factory.
- Program the Robot – The first step is to program the robot with specific welding tasks, including the type of weld, the path it will follow, and the speed at which it will work.
- Position the Parts – Parts to be welded are positioned in a fixture or assembly line.
- Execute the Weld – The robot’s arm moves to the designated position and performs the weld, ensuring precise alignment and temperature control.
- Quality Check – Post-weld, the robot or another system performs a quality check to ensure there are no defects in the weld.
Applications of Welding Robots
Welding robots are used across various industries, from automotive manufacturing to shipbuilding. Let’s explore some of the key sectors that benefit from robotic welding technology:
