The welding of EH36 steel requires appropriate procedure control to achieve consistent joint quality, particularly when thick plates and highly restrained structural connections are involved. In shipbuilding, welding parameters are normally established through approved procedures covering the specific material thickness and joint configuration.
Manual and mechanized welding processes can be selected for EH36 steel plate according to the requirements of the production line. Consumables should be compatible with the specified material and joint requirements, while welding parameters such as current, voltage, travel speed, and heat input should remain within the approved procedure range.
For heavier sections, preheating may be required depending on plate thickness, joint restraint, hydrogen control, ambient conditions, and the applicable welding procedure. Interpass temperature should also be monitored during multi-pass welding to maintain consistent conditions throughout the joint.
Assembly sequence is particularly important when large EH36 steel panels are joined. Improper sequencing can introduce unnecessary distortion and residual stress, affecting the dimensional accuracy of hull sections and other structural assemblies. Planned tack welding, positioning, and welding sequences can help maintain alignment during production.
After welding, completed joints can be inspected according to the vessel's quality control plan. Visual inspection and applicable nondestructive testing methods may be used to verify weld quality, with additional inspection requirements determined by the classification society and project specifications.
For hull panels, bulkheads, deck structures, and other major assemblies, reliable results depend on coordinated control of material preparation, welding procedures, assembly sequence, and inspection. The exact welding parameters for EH36 steel plate should always be confirmed through the approved project procedure rather than applying a general set of conditions to every application.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
