Abstract：In order to solve such problems that the carbon arc gas gouging and plate rolling in the welding process of abutting plate lead to the complex procedure and low efficiency as well as the automatic welding can not be realized,the method such as single-side submerged arc welding plus ceramic liner was proposed. The submerged arc welding was performed for the front side of plate unit,the back side of plate was closely fitted with the ceramic liner,and thus the single-side welding and double-side shaping could be realized. The research results show that the proposed technology can completely meet the requirements in both 100% radiographic testing and 100% ultrasonic testing. The impact absorbing energy is above 27 J at -20℃ and the mechanical properties meet the standard requirements. Compared with the traditional technologies,the proposed welding technology can ensure the welding quality, simplify the production process, improve the production efficiency,decrease the production cost,reduce the environmental pollution and realize the green production.
