Welding robots began to be used only in spot welding. With the development of computer technology and sensor technology, arc welding robots have gradually gained popularity. Welding robots have been widely used in automobiles, motorcycles, construction machinery and other fields.
When the welding robot is welding, the operator must teach the trajectory of the robot welding gun and set the welding conditions. Because of the need to teach, the robot is not suitable for welding products of many varieties and small quantities. Second, the accuracy of the workpiece must be ensured, because the robot has no eyes and can only repeat the same action.
The trajectory accuracy of the welding robot is ± 0.1 mm, and the same action is repeated with this accuracy. When the welding deviation is greater than the welding wire radius, the welding may not be good, so the workpiece accuracy should be kept within the welding wire radius. The setting of welding conditions depends on the technical level of the teaching operator. When teaching, the operator must enter the welding procedure, welding torch attitude and angle, current, voltage, speed and other welding bars. The teaching operator must fully grasp the welding knowledge and Welding skills.
Welding robots must pay full attention to safety during the welding process. It is a high-speed sports equipment. It does not allow people to approach the robot during its automatic operation. A safety guard must be installed. Operators must receive special education on labor safety, otherwise they are not allowed to operate.
