Fiber laser welding machine is a laser welding equipment that couples a high-energy laser beam into an optical fiber, collimates it into collimated light through a collimator, and then focuses on the workpiece to perform welding after long distance transmission. For the parts that are difficult to access by welding, non-contact welding with flexible transmission is implemented, which has greater flexibility. The laser beam can achieve time and energy splitting, and it can process multiple beams
