The control methods of welding robots mainly rely on good sensing technology, vision systems, adaptive control algorithms, and intelligent control systems. Through sensing technology, robots can monitor the position, shape, and size of welds in real time, and adjust the wire feeding speed to adapt to changes in the welding path. Meanwhile, an excellent visual system can capture weld seam images, extract welding path information, and ensure that the welding wire is welded in the correct position. The adaptive control algorithm automatically adjusts welding parameters such as current, voltage, and welding speed according to the different requirements of the welding task to maintain the consistency of the weld seam. Intelligent control systems can learn and adapt to different welding tasks, continuously optimize control strategies, and improve welding accuracy and efficiency.
