There are many ways to apply high-frequency welding H-shaped steel, such as railway station canopy, steel structure plant, public building, steel structure housing, airport exhibition hall, light rail subway guardrail, industrial equipment support, greenhouse and farm, livestock farm, membrane structure and Grid structure construction works and so on.
High Frequency Welding H-shaped Steel Features Overview
The welding speed is quick and the heat effect is small. It is easy to control the change of H-shaped steel, weld H-shaped steel with different material combinations, realize micro-tensile production, and reduce welding stress.
High-frequency welding H-shaped steel five characteristics
1, a wide range of specifications (cross-sectional size). The height, web, flange thickness and flange width can be selected according to customer's requirements. Can be used for hot-rolled H-beam outside the standard.
2, choose a variety of steel. Hot-rolled H-section steels are mainly Q235B and Q345B. When special steels in small batches are required, the production plant cannot produce them. Welding can be selected as needed.
3, the product has high precision and good surface quality. Due to the high precision of the steel plate products and the good surface quality, the H precision after welding is also high and the surface quality is also good. The thickness deviation of the steel plate (used to weld H-shaped steel) is generally from a few tenths of millimeters to a few tenths of a millimeter, while the thickness deviation of hot-rolled H-beams is a few tenths of a millimeter to one millimeter, a difference of nearly ten times.
4, stable performance, good internal organization. Because from smelting to continuous casting to rolling, the production of steel plates is higher than that of hot-rolled H-beams, equipment capacity, control level, and detection methods. Therefore, the internal structure, chemical composition, and various properties (mechanical properties, process properties, etc.) of welded H-beams ) The indicators are reliable and stable.
5, easy to have welding defects. Although there are many advantages mentioned above, due to the welding forming, there is residual welding thermal stress in the welding zone, the welding zone is different in organization, there is a structural stress, and welding defects are easily generated. With the continuous improvement of the level of welding and heat treatment, these disadvantages are gradually reduced. Nowadays, high-quality welded H-shaped steel has been applied to various fields including military and aerospace.
Q345b high-frequency welding H-beam steel supplier----Wuxi Hongbotai Metal Products Co., Ltd.
Q345b high-frequency welding H-beam product features
Why is q345b high-frequency welded H-shaped steel so popular in the market? Because high-frequency welding of H-beams is the foundation of a building, good construction engineering is inseparable from good high-frequency welding H-beams.
