The invention discloses a hydrogen mixing pipeline automatic submerged arc welding auxiliary device and process, and belongs to the technical field of submerged arc welding, the hydrogen mixing pipeline automatic submerged arc welding auxiliary device comprises a base, the base is provided with a fixing assembly, a switching assembly, an auxiliary assembly and a detection assembly, and through mutual cooperation of the switching assembly and the auxiliary assembly, under the action of a laser cutting machine, the automatic submerged arc welding of a hydrogen mixing pipeline is achieved. The end of the hydrogen mixing pipeline can be subjected to laser cutting before welding, so that it is guaranteed that the front welding end of the hydrogen mixing pipeline is in a flat state, through mutual cooperation of the detection assembly and the auxiliary assembly, the sealing performance of a welding seam can be detected after welding is completed, and if an unqualified condition occurs, the detection efficiency is i
