The invention relates to the technical field of laser electrical arc welding, in particular to a hybrid welding continuous welding method and device, a welding finished product and a vehicle body. Thehybrid welding continuous welding method comprises carrying out hybrid welding on the groove of a weldment through laser and polarity-changing electric arc coupling, wherein the defocusing amount oflaser is less than the rayleigh range of laser. With adoption of the hybrid welding continuous welding method, the laser power density on the surface of the weldment is effectively reduced, the depth-to-width ratio of a welding seam is reduced, the diameter of a welding molten hole is increased, the hole of the welding molten hole caused by the small hole collapse phenomenon is effectively reducedto solve the problem in the prior art that the welding bubble is difficult to escape, generation of a hydrogen hole is reduced, the welding stability and reliability are effectively reduced, and themechanical property of the welding seam is improved.
