High frequency welded H-section steel

High frequency welding H-beam uses the two characteristics of "surface effect" and "proximity effect" of high-frequency current to place the two contacts in the low impedance channel of the welded material through contact conduction, that is, all current flows from the V-shaped opening formed by the upper and lower flanges and the web, so that the welding power at the V-shaped opening is relatively concentrated, The welding of H-section steel is realized with small welding power.

Process characteristics of high frequency welding H-section steel:
1. The accuracy of section size is high, which makes the structural assembly more convenient.
2. High precision of section performance: the ratio of flange plate to web thickness can be increased. Compared with compressive stiffness, components with greater flexural performance and higher interface performance can be made under the same weight; When the interface performance is the same, the construction is lighter.
3. The section size can be customized according to the user's requirements.
4. The metallographic structure of the welding part is uniform.
