Laser welding machine (UW-600A)

Energy negative feedback: The working principle of an energy negative feedback laser welding machine is to add an energy detection device at the output end of the laser to detect the magnitude of the laser energy and provide real-time feedback to the control end. The signal is compared with the theoretically set energy to form a closed-loop control system, achieving accurate control of the laser energy output. As follows: 1. Energy negative feedback technology can make the energy output of the laser have good repeatability. Simply put, it can ensure the stability of the laser energy output each time, which can effectively reduce the defect rate of the product. 2. The output waveform can be set arbitrarily according to the welding material, shape, etc. during the welding process of specific workpieces. By changing the output waveform of laser energy based on the shape and material of the work, the welding quality can be greatly improved. Even some traditional laser welding problems can be solved by changing the output waveform of the laser. 3. Laser can achieve multi fiber simultaneous output, which increases the degree of freedom in processing compared to traditional hard path output systems. It can perform multi beam simultaneous processing and multi station processing, providing conditions for more precise welding.
