Precautions for box column welding

In order to ensure the stability of the electroslag welding process and the quality of the welding, the five key links including installation and equipment adjustment, arc slag production, normal welding and welding seam closing should be completed continuously, and try not to stop in the middle.

What are the characteristics of welded H-shaped steel?

Light weight of the structure: It is lighter than the weight of the concrete structure. The reduction of the weight of the structure reduces the internal force of the structural design, which can make the foundation processing requirements of the building structure lower, the construction is simple, and the cost is reduced.

Application scope of welded H-shaped steel

H-shaped steel is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.

What are the advantages of welding H-shaped steel?

It can be processed, designed and combined at will according to the project, and special specifications can be manufactured to meet the actual needs of special projects. H-shaped steel specifications have been economically designed. Its section moment, section coefficient, pressure resistance and load-bearing capacity are much higher than those of the same unit. Weight of hot rolled steel.
