For the welding of API Std 650 duplex stainless steel tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API Std 650 duplex stainless steel tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.
