Before welding the vertical liquid oxygen storage tank, a welding process qualification should be conducted in accordance with the “Welding Process Qualification for Steel Pressure Vessels” (JB4708-2000) and the “Construction and Acceptance Specifications for Vertical Cylindrical Steel Welded Storage Tanks” (GBJ128-1990). Additionally, based on the design requirements of the drawings, first determine the appropriate welding process parameters by conducting the welding performance tests of the materials in accordance with the current national “Welding Performance Test” standards, taking into account the construction factors such as steel grade, plate thickness, welding method, and welding materials.
