What is welded beams?

H – beam, is a structural component widely used in construction2. It is named because its cross – section is in the shape of the English letter “H”1. H – beam is an economical and high – efficiency profile with a more optimized cross – sectional area distribution and a more reasonable strength – to – weight ratio1.

Manufacturing Process of welded beams

• Резка: Before welding the web and flange plates of H Beam, use a leveling machine to level the steel plates. The cutting equipment mainly uses a flame multi – head straight strip cutting machine. Multiple plates are cut at the same time to prevent side bending of the parts after cutting. It is necessary to check the material, specification, and size of the steel plate, and remove rust, oil, and other debris on the surface. After cutting, the oxide scale and sulfur residue on the cutting surface should be removed.
• Assembly: Mark the center line of the flange plate and the positioning line of the web plate. Check the correctness of the flange plate, web number, material, size, and quantity. Assemble the T – shaped flange plate and web plate on the H – shaped steel automatic assembly machine and perform positioning welding, and then assemble the T – shape and the other flange plate to form an H – shape. The joints of the flange plates and the web joints should be staggered by more than 200 mm. The platform and tire frame for assembly should meet the accuracy requirements and have sufficient strength and stiffness.
• Сварка: Weld the assembled H – shaped steel components. The positioning weld should not have cracks or pores, and it must be performed by welders with corresponding certificates. The welding materials are the same as those for formal welding. When pre – heating is required, the pre – heating temperature should be higher than that for formal welding.
• Correction: After welding, correct the H – shaped steel to ensure that its shape and size meet the design requirements.

Advantages of welded beams

• High Structural Strength: Due to its reasonable cross – sectional shape, H – shaped steel has strong bending resistance in all directions, and can withstand large loads, which is suitable for various large – scale building structures and engineering projects.
• Lightweight Structure: Compared with other steel structures with the same bearing capacity, H – shaped steel has a lighter weight, which can reduce the overall weight of the structure, reduce the foundation load, and save materials.
• Simple Construction: H Beam components are easy to process and manufacture, and the on – site assembly is convenient and fast, which can significantly shorten the construction period and improve the construction efficiency.
• Flexible and Rich Design Styles: It can be designed and processed according to different engineering needs, and is suitable for various structural forms, providing a wide range of space for architectural design.
• High Structural Stability: The flanges on both sides of H – shaped steel are wide and perpendicular to the web, which has good stability when bearing bending moment and shear force, and can ensure the safety and stability of the structure.
• Environmental Protection: H – shaped steel has a high degree of industrial production, and the construction process produces less waste. At the same time, it is recyclable, which is in line with the requirements of environmental protection.
