Function of  Welding Robots

1. Position finding function. The end positioning function is indispensable for workpieces with large tolerances or poor assembly accuracy. The positioning device has a wire package that can generate tens of volts. Position finding is the momentary short circuit caused by the welding wire contacting the workpiece, that is, the robot system finds the three-dimensional coordinates of the point of the actual workpiece weld. In this way, the robot system detects multiple points and calculates the deviation value based on these points. , Use the deviation value to modify the position data of the originally taught weld seam, so as to obtain the position of the actual weld seam starting point.

2. Arc tracking function. During the welding process of the welding robot, due to the influence of various factors in the welding environment, such as processing error, fixture installation accuracy, surface condition, spatter and thermal deformation of the workpiece, the actual welding path deviates from the original teaching path, resulting in Welding quality has deteriorated or even failed. The arc tracking function is to measure the changes in the welding current during the welding process, and then the robot automatically calculates the data generated by the arc swing during the welding process to obtain the exact position of the weld and correct the welding path.

3. Arc restart function. After the workpiece is extinguished due to unexpected circumstances, it can carry out the arc starting action of the equipment times in advance, thereby reducing the pause time and improving the production efficiency.

4. Welding torch recovery function. The torch recovery function is a function that automatically corrects the deviation of the tip position of the welding torch wire in a short time. By using this function, the downtime can be shortened and stable welding quality can be obtained.

5. Database function. The database includes a welding expert database and a database compiled by the user. The powerful expert database includes the weld form of the workpiece to be welded and the corresponding process parameters. Calling the expert database greatly simplifies teaching workload and improves work efficiency.

Users can also call or modify the process parameter table according to their own process requirements, so as to achieve the desired effect.

6. Various forms of weaving welding function. For medium and thick plates, it is generally necessary to swing during manual welding. At this stage, the welding robot also provides various forms of swing welding functions, such as: SIN swing, circular swing, and eight-shaped swing. In the setting of swing parameters, the user can define the swing amplitude, frequency, and stop time at the end of the swing by himself.

7. Anti-collision function. The collision function refers to the function that can prevent the various joints of the robot from colliding with the workpiece or the positioner due to the unreasonable operation. In addition, according to the actual welding conditions, you can select the positioner idling avoidance function, the regeneration temporary stop automatic recovery function, and the nozzle contact avoidance function.
