The invention discloses a laser welding method for metal linings of spherical high-pressure gas cylinder walls, and belongs to the technical field of metal material fusion welding. The laser welding method for the metal linings of the spherical high-pressure gas cylinder walls comprises the steps of arranging first bottom-locking steps at the joints between filler necks and lining bodies and arranging circular seam connection rings at the joints of the lining bodies, wherein filter screen assemblies comprise filter screens and filter screen reinforcing rings and the filter screen reinforcing rings are arranged on the two sides of the edges of the filter screens; welding the filler necks to inner holes of the lining bodies through the first bottom-locking steps; welding the filter screens into the lining bodies through the filter screen reinforcing rings; welding the lining bodies through the circular seam connection rings. According to the laser welding method for the metal linings of the spherical high-press
