Large-diameter pipe laser welding equipment

The invention relates to the technical field of laser welding equipment, in particular to large-diameter pipe laser welding equipment which comprises a translation structure, a mounting frame, a rotating structure, a fixing structure, an adjusting structure, a laser welding structure and a driving structure. The rotating structure used for driving the pipes to rotate is provided with the fixing structure used for fixing the pipes, a forklift or a lifting appliance is conveniently used for carrying the two pipes into the fixing structure, the pipes are fixed through the fixing structure, meanwhile, the pipes are located at the center position of the rotating structure, and the driving structure drives the rotating structure to drive the pipes to rotate. The welding position can be visually reflected conveniently, when faults occur, loss is reduced, a mounting frame is fixed to the translation structure, the horizontal position of the mounting frame can be adjusted conveniently due to the arrangement of the tra
