How Laser Welding Machine Works
The operation of a Laser welding machine involves a series of steps that are crucial for achieving high-quality welds. Initially, the laser source generates a coherent light beam, which is directed through the optics system to focus the beam onto the workpiece. This focused beam has enough energy to melt the material, creating a molten pool. As the machine moves the beam across the workpiece, this molten pool solidifies, forming a strong bond as it cools. The control unit plays an integral role, adjusting parameters such as the speed of the movement and power of the laser to ensure precise welding results.
