[0002] LNG cryogenic storage tanks are used to store liquefied natural gas. The material used for the tank body is nine-nickel steel. The effective welding of nine-nickel steel is critical to the safety and reliability of LNG storage tanks. During the rolling and processing of nine-nickel steel, due to the influence of the external magnetic field, magnetic accumulation will inevitably occur, resulting in excessive residual magnetism. The most commonly used welding method for the annular seam of the storage tank is submerged arc automatic welding. Since automatic welding has very high requirements for the residual magnetism of the groove part of the steel plate, the residual magnetism of the groove part cannot exceed 30 Gauss, otherwise magnetic blow will occur when the automatic welding is initiated at a sharp angle, causing the weld to deviate and cause welding failure. Therefore, the residual magnetism of nine-nickel steel has also become one of the key process indicators.
