Description

Technical Field

[0001] The utility model belongs to the technical field of welding of lattice shells of arched roof storage tanks, and in particular relates to a bracket for welding lattice shells of arched roof storage tanks. Background Art

[0002] The dome tank lattice shell is a cylindrical or hemispherical tank structure for storing liquids or gases. It is characterized by an arched top and downward sloping sides to ensure the stability of the gas or liquid pressure inside the tank. The lattice shell structure of the dome tank lattice shell is composed of many reinforced concrete or steel beams and columns to form an integral lattice structure. This structure has good rigidity and strength and can withstand large internal pressure. The welding of the dome tank lattice shell is a very important link in the manufacturing process of the dome tank, which is related to the safety performance and durability of the tank. During the welding process, certain welding specifications and requirements need to be followed to ensure the quality of welding. According to the tank material and welding process requirements, select the appropriate welding material. For the welding of the dome tank lattice shell, manual arc welding and automatic welding can generally be used. Parameters such as welding current, voltage, and welding speed should be reasonably set according to factors such as welding materials, electrode type, weld shape and position. At the same time, the welding parameters should be adjusted according to the actual situation. When welding the lattice shell, it should be carried out in a top-to-bottom and left-to-right order. This can ensure that the welding stress during the welding process is effectively released and avoid welding deformation. After welding is completed, the weld should be inspected by appearance inspection, non-destructive testing and other quality inspections to ensure that the weld quality meets the relevant standards and design requirements. After welding is completed, the weld should be cleaned, rust-proofed, and anti-corrosion treated to ensure the long-term stability and durability of the weld.
