[0008] Compared with existing technologies, the advantages of this invention are: the welding fixture has a stable structure and high positioning accuracy, effectively ensuring the stability and accuracy of the welding process. Cooling water is circulated in the cooling table of the fixture, and the top surface of the cooling table contacts the large plate. Forced cooling through the circulating water cooling of the welding area rapidly reduces thermal stress, disperses welding stress, and significantly reduces deformation of the large plate during the welding process. This greatly reduces the workload and time required for manual welding, and the welding efficiency of this invention is 10 times that of manual welding. Attached Figure Description
