The multi-axis platform laser welding machine is an automated equipment that integrates a high-precision multi-axis motion control system with laser welding technology. Through multiple linkage axes (usually including X/Y/Z linear axes and A/B/C rotation axes), the workpiece can be positioned at any angle in three-dimensional space and welded on complex trajectories. Its core principle is to use a high-energy laser beam to focus on the surface of the material, instantly melt the metal to form a molten pool, and form a high-strength weld after cooling. Multi-axis linkage technology is the core innovation. Through the CNC system, the movement of each axis is coordinated to meet the welding needs of complex curved surfaces and special-shaped structures, and to solve the interference problem caused by insufficient degrees of freedom in traditional welding.
