High-frequency welded H-beam
High-frequency welded H-beam (HFW H-beam) is widely used in modern construction and industry due to its high strength and excellent welding performance.
1. Advantages
① High strength: The strength of the weld is equivalent to that of the parent material, ensuring the bearing capacity of the structure.
② Save materials: The weld joint has high strength, which can reduce materials and reduce costs during design.
③ Fast welding speed: The process speed is fast, which improves efficiency and is suitable for large-scale production.
④ Smooth surface: The weld is flat, without obvious defects, and meets the aesthetic standards.
2. High-frequency welded H-beam standards
Standard type | Standard name and description |
Material standard | GB/T 700 (carbon structural steel) |
GB/T 1591 (low alloy high strength structural steel) | |
