Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of standard welding robots for industrial robots by the International Organization for Standardization (ISO), an industrial robot is a multi - purpose, reprogrammable automatic control manipulator with three or more programmable axes, used in the field of industrial automation. To adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange, which can be equipped with different tools or end - effectors.
1. Select a reasonable welding sequence to reduce welding deformation and the length of the welding torch's travel path when formulating the welding sequence.
2. The space transition of the welding torch requires a short, smooth and safe movement trajectory.
3. Optimize the welding parameters. To obtain the best welding parameters, make test workpieces for welding tests and process evaluations.
4. Adopt a reasonable position of the positioner, the posture of the welding torch and the position of the welding torch relative to the joint. After the workpiece is fixed on the positioner, if the weld is not in the ideal position and angle, the positioner needs to be continuously adjusted during programming so that the welds to be welded reach the horizontal position one by one according to the welding sequence. At the same time, the positions of each axis of the robot need to be continuously adjusted to reasonably determine the position and angle of the welding torch relative to the joint and the extension length of the welding wire. After the position of the workpiece is determined, the position of the welding torch relative to the joint must be observed by the programmer's eyes, which is quite difficult. This requires the programmer to be good at summarizing and accumulating experience.
5. Insert the gun - cleaning program in time. After writing a certain length of welding program, the gun - cleaning program should be inserted in time, which can prevent welding spatter from blocking the welding nozzle and the contact tip, ensure the cleanliness of the welding torch, increase the service life of the nozzle, ensure reliable arc ignition and reduce welding spatter.
6. Generally, programming cannot be completed in one step. The program needs to be continuously inspected and modified during the robot welding process, and the welding parameters and the posture of the welding torch need to be adjusted to form a good program.
