The invention relates to the technical field of laser welding machines and discloses an efficient and annular multipath laser-beam welding machine. The efficient and annular multipath laser-beam welding machine comprises a bearing plate. A hydraulic telescopic rod is arranged at the center of the top of the bearing plate; a stripe plate is arranged on the top of the hydraulic telescopic rod; a welding machine body is arranged on the left side of the bottom of the stripe plate; a first slide block is fixedly mounted in the bottom of the hydraulic telescopic rod; and a first chute correspondingto the first slide block is formed in the top of the bearing plate. According to the efficient and annular multipath laser-beam welding machine provided by the invention, the stripe plate moves frontand back on hydraulic telescopic rod by way of the first slide block and the first chute, and meanwhile, the stripe plate can rotate at 360 degrees on the hydraulic telescopic rod by way of the firstbearing. The two modes are matched in use at the same time, so that the welding efficiency can be increased effectively, the welding quality can be improved effectively, and the percent of pass of theproduct can be increased effectively.
