Welding turntable device

The utility model relates to a welding turntable device, relates to the technical field of air conditioning equipment, and is used for solving the problems of lower welding and piping efficiency and higher labor intensity of personnel during welding and piping of large components. Comprising a rotary table used for placing a to-be-welded part; the driving mechanism is connected with the rotary table and used for driving the rotary table to rotate; the inflation pipeline is arranged on the rotary table; wherein the inflation pipeline is constructed to be capable of introducing welding protection gas into the welding part of the to-be-welded part when the to-be-welded part is welded on the rotary table, so that the welding part is prevented from being oxidized. The driving mechanism and the rotary table are arranged, and the rotary table is driven by the driving mechanism to rotate. In this way, the to-be-welded part can rotate around the central axis of the rotary table, and the operation part of the to-be-wel
