Background

Ocean platforms provide a structure of production and living facilities for activities such as drilling, oil extraction, gathering, observation, navigation, construction, etc. at sea. The pile foundation type and gravity type are divided according to the supporting condition, and a pile foundation platform which is applied to a soft soil foundation is composed of an upper structure (namely a platform deck) and a foundation structure. The superstructure is typically comprised of upper and lower deck decks and inter-floor trusses or columns. The deck is provided with a drilling device, an auxiliary tool, a power device, a mud circulation purifying device, personnel work and living facilities, a helicopter lifting platform and the like. The size of the platform deck is determined by the use process. The infrastructure (i.e., substructure) includes jackets and piles.

Submerged arc welding (including submerged arc overlay welding, electroslag overlay welding, etc.) is a method in which an arc is burned under a flux layer to perform welding. The inherent advantages of stable welding quality, high welding productivity, no arc light, little smoke dust and the like make the welding method become a main welding method in the manufacture of important steel structures such as pressure vessels, pipe section manufacture, box-type beam columns and the like.
