Optical fiber transmission laser welding machine is a kind of laser welding equipment which couplings high energy laser beam intooptical fiber, and after long distance transmission, collimates parallel light through collimator to perform welding on theworkpiece. For the parts that are hard to get close to welding, the simple universal direction instrument can be used to dock thelarge mould and the precise parts that are hard to get close to, and carry out the flexible transmission non-welding,whichhas greater flexibility.The laser beam can split light in time and energy, and can process multiple beams at the same time,whichprovides conditions for more precise welding.
