Which manufacturer has good quality high-frequency welded H-beams?

High frequency welding H-beam production line has strong continuous production capacity and high production efficiency. It has online detection, online straightening, online fixed length shearing and other equipment. Compared with submerged arc welding and gas shielded welding, the production technology is more progressiveness.

Advantages:

High precision in cross-sectional dimensions makes structural assembly more convenient.

The cross-sectional performance is excellent, and the ratio of flange plate to web plate thickness can be increased. Compared with compressive steel, it can be made into components with greater bending resistance and higher cross-sectional performance under the same weight conditions; When the cross-sectional performance is the same, the component is lighter;

The cross-sectional size can be customized according to the user's size;

The microstructure of the weld bead at the welding site is uniform.


High frequency welding of H-shaped steel


The technical characteristics of high-frequency welding of light H-shaped steel are:(1) fast welding speed, up to 18-45m/min; (2) Low thermal impact, easy to control deformation of H-beam; (3) H-shaped steel with different material combinations can be welded; (4) It can achieve micro tension production and reduce welding stress. Technical level:(1) High accuracy of cross-sectional dimensions; (2) Excellent cross-sectional performance; (3) The cross-sectional dimensions can be customized according to user requirements

When the specifications and materials are consistent, hot-rolled H-shaped steel can completely replace welded H-shaped steel, and the former has guaranteed quality compared to the latter. Generally, in structural design, hot-rolled H-shaped steel should be used for high-rise buildings. For light steel factories with portal frame structures, welded variable cross-section H-shaped steel has better steel consumption indicators, but the engineering cost cannot be saved much. The reason is that the processing volume of hot-rolled H-shaped steel is smaller and the construction period is slightly shorter, If the comprehensive economic benefits (including after the project is put into use) are calculated, hot-rolled H-beams can be selected when the construction period plays a decisive role. However, when the construction period requirements are not strict or some visual projects are not strict, welded H-beams can be selected based on the principle of resource conservation
