Description
Welding robots are a type of articulated robot with a welding torch mounted at the end effector. This torch is supplied with consumable wire and shielding gas. Welding robots allow for the automation of welding processes, significantly improving both quality and productivity. They are capable of performing straight, circular, and ring welds. Key advantages of using welding robots include:
-
Reduced time for performing repetitive welding operations;
-
Precise weld seams along any trajectory;
-
Lower energy and consumable costs;
-
High-quality welds;
-
Reduced workforce requirements.
There are several types of welding robots:
-
Welding robots using consumable electrodes (wire) in argon and carbon dioxide shielding gases. These systems allow for different wire diameters and current strengths, enabling welding of metals with various thicknesses. Such robots are commonly used on automobile assembly lines.
-
Welding robots using non-consumable tungsten electrodes, suitable for welding copper and stainless steel.
-
Welding robots for contact welding using carbon electrodes, mainly used in the machinery and electrical appliance industries.
-
Welding robots for welding hard-to-weld materials with a plasma jet.
-
Welding robots for pipeline welding using consumable electrodes under flux.
-
Laser welding robots, which allow for high-speed welding of metals without emitting harmful substances into the air.
Before the welding robot begins operation, an operator sets it up for the specific joint and weld type, entering parameters such as weld length, current, and torch travel speed. There are two main methods for automating workpiece feed to the robot: either manually by an operator or via a conveyor system or another robot. Robot programming is done via a control pendant. Axis calibration must be performed prior to first use — a one-time procedure when setting the robot into its initial working position. The robot’s motion range is checked and matched to the settings in the control panel. Then the tool coordinates are set, followed by the surrounding environment coordinates. This ensures the robot can move freely without colliding with parts or other objects.
Welding robots are represented by over ten models in the Arc Mate series, designed specifically for arc welding, laser welding, soft soldering, and cutting operations. Welding robots support payloads from 3 to 20 kg. They feature a slim arm with a hollow wrist, enabling operation in tight spaces even with heavy tools. Their plug-and-play interface allows easy connection to all major power supply units. Power supply parameters can be monitored and adjusted directly from the Robot iPendant control panel. Welding robots can also be equipped with the iRVision system, which allows the robot to identify part types, part and weld seam positions, and even perform post-weld inspections.
