The invention discloses an axial point ring multi-focus laser welding method, and belongs to the technical field of laser welding. Compared with a traditional welding method that a central light beam focal plane, a ring light beam focal plane and a beam combining surface of a point ring laser beam are usually coincident, the point ring laser beam is formed by coupling a central light beam distributed in a waist shape and a ring light beam distributed in an inverted cone shape; the central light beam focal plane of the point-ring laser beam shaped by the optical element is positioned below the ring light beam focal plane, and the central light beam light spot and the ring light beam light spot are overlapped at a beam combining surface below the central light beam focal plane. In this way, the fusion depth is maintained through the beam combining face light spots, the center light spot of the center light beam focal plane penetrates through the small hole and bubbles during collapse, the ...
