What Are The Characteristics Of Welding Robots?

Welding Robotics are Industrial Robots engaged in welding (including cutting and spraying). According to the International Organization for Standardization (ISO), industrial robots are defined as standard welding robots. Industrial robots are a multi-purpose, reprogrammable automatic control manipulator (Manipulator) with three or more programmable axes for 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 with different tools or end effectors. Welding robots are equipped with welding tongs or welding (cutting) guns on the final shaft flange of industrial robots to enable welding, cutting or thermal spraying.

Spot Welding Robot TKB1900

We learned from Welding Robot Suppliers that spot welding does not have high requirements for welding robots.Because spot welding only needs point control, there is no strict requirement for the welding trajectory of the welding tongs from point to point, which is why the robot can only be used for spot welding at the earliest. Not only must the robot for spot welding have sufficient load capacity, but also the speed when moving from point to point should be fast, the movement should be smooth, and the positioning should be accurate to reduce the time of displacement and improve work efficiency. How much load capacity the spot welding robot needs depends on the type of welding tongs used. For welding tongs separated from the transformer, a robot with a load of 30 to 45 kg is sufficient. However, on the one hand, due to the length of the secondary cable and large power loss, this welding tong is not conducive to the robot extending the welding tong into the workpiece for welding; on the other hand, the cable sways with the robot's movement and the cable is damaged faster . Therefore, the use of integrated welding tongs is gradually increasing. The quality of this welding clamp together with the transformer is around 70kg. Considering that the robot must have sufficient load capacity, the welding tongs can be sent to the space position for welding with a relatively large acceleration. Generally, a heavy robot with a load of 100 to 150 kg is selected. In order to meet the requirements of rapid displacement of welding tongs in short distance during continuous spot welding. The new heavy-duty robot adds the ability to complete a 50mm displacement in 0.3s. This puts forward higher requirements on the performance of the motor, the calculation speed and algorithm of the microcomputer.
