Swing welding is a welding method that simulates the swinging action during manual welding to improve the quality and efficiency of welding. In the KUKA robot welding system, swing welding technology has been widely used and developed. This technology controls the robot to swing regularly during the welding process through preset swing trajectories and parameters, thereby achieving uniform heating and shaping of the weld and improving the welding quality.
KUKA robot’s oscillating welding technology enhances welding quality. The robot can be programmed to move the welding torch in an oscillating pattern. This improves the fusion of materials and the distribution of the weld bead. By adjusting parameters like oscillation amplitude and frequency, different welding requirements are met. It also helps cover a wider area, reducing welding time and ensuring consistent results.
- Working principle
The working principle of KUKA robot swing welding is mainly based on advanced control system and sensor technology. Through integrated control system, motion control technology, welding control technology and actuator, KUKA robot can achieve high-precision, high-speed and high-stability swing welding operation.
During the welding process, KUKA robot controls the welding gun to swing regularly according to the preset swing trajectory and parameters. At the same time, the welding status is monitored in real time through external sensors, such as weld tracking, molten pool monitoring, etc., to further ensure the stability and accuracy of the welding process. In addition, KUKA robot also adopts advanced power control technology, which can accurately adjust parameters such as current and voltage according to welding requirements to meet the needs of different welding processes. - Parameter setting
The setting of swing welding parameters has a vital impact on welding quality and efficiency. In the KUKA robot welding system, users can select the appropriate swing type according to actual needs, and set the corresponding swing length, swing amplitude, swing frequency and other parameters.
Swing type: KUKA robot supports a variety of swing types, including no swing, triangular swing, double triangular swing, trapezoidal swing, double trapezoidal swing, asymmetric trapezoidal swing, double figure eight swing, etc. Users can choose the appropriate swing type according to the shape and size of the weld.
Swing length: The swing length refers to the distance from one extreme position to another extreme position of the welding gun during the swing process. The setting of the swing length needs to be adjusted according to the length and width of the weld to ensure uniform heating and shaping of the weld.
Swing amplitude: The swing amplitude refers to the maximum offset of the welding gun relative to the center position during the swing process. The setting of the swing amplitude needs to be adjusted according to the width and depth of the weld to ensure the filling effect and appearance quality of the weld.
Swing frequency: The swing frequency refers to the number of swing cycles completed by the welding gun per unit time. The setting of the swing frequency needs to be adjusted according to the welding speed and the quality requirements of the weld to ensure the stability and efficiency of the welding process. - Operation steps
