Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of a standard welding robot by the International Organization for Standardization (ISO), an industrial robot is a multi-purpose, reprogrammable automatic control operator with three or more programmable axes for use in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be connected to different tools or end effectors. The welding robot is equipped with a welding clamp or welding (cutting) gun on the final shaft flange of the industrial robot to enable it to weld, cut or thermal spray. So do you know what types of welding robots there are?
Welding robots are classified into different types based on their drive systems. Hydraulic drive and pneumatic drive welding robots are the two major types of robots that are commonly used in the industry. In addition to these, electric drive welding robots are also gaining popularity due to the improvements in the motor technology.
Hydraulic drive welding robots are powered by a hydraulic pump that generates high pressure oil. The high-pressure oil is then used to power the hydraulic motor that provides the required torque. Hydraulic drive welding robots are known for their high precision, accuracy, and repeatability.
Pneumatic drive welding robots, on the other hand, use compressed air to power the motors. Pneumatic drive systems are known for their high speed and low maintenance requirements. They are also more cost-effective than hydraulic drive systems.
Electric drive welding robots are powered by different types of electric motors such as AC motors, AC servo motors, and DC motors. Recent advances in motor technology have led to the development of more efficient and reliable electric drive systems. Electric drive systems are known for their high speed, accuracy, and energy efficiency. Moreover, they are easier to maintain and operate than hydraulic or pneumatic drive systems.
In summary, welding robots come in different types based on their drive systems. Hydraulic drive welding robots are known for their high precision, while pneumatic drive welding robots are more cost-effective and require less maintenance. Electric drive welding robots are gaining popularity due to their high speed, accuracy, and efficiency. Overall, the choice of a welding robot largely depends on the specific application and the requirements of the manufacturing process.
