From the standpoint of rolling process, the difference between the H-beam and the ordinary I-beam is that the I-beam can be rolled in the two-roll pass, while the H-shape can be rolled in the universal pass. However, the hot-rolled h-beams produced using the near-net-shape continuous casting blank and the four-roll universal rolling method have the advantages of excellent quality, low environmental protection and low cost, and can significantly improve the quality of the steel. The welding of H-shaped steel means that strips of suitable width and thickness are placed on a continuation welding unit and they are welded together. This process consumes more material and the production speed is slower.
High-frequency welding of thin-wall H-shaped steel is mainly based on high-frequency current melting melt billet, welding the product surface will not be oxidized, the quality is far better than gas welding; its welding frequency is high, and welding The heat affected zone is small, and the shape of the H-shaped steel can be more conveniently controlled; high-frequency welding can combine different steels to form different high-frequency welded thin-walled H-shaped steels. It has many advantages, such as: more accurate and comprehensive specifications, can meet the requirements of customers to the greatest extent; fast shipping, easy installation and so on.
Whether it is high-frequency welding thin-wall H-beam or hot-rolled H-beam have their own unique advantages and disadvantages, in the use of the process can only be based on the actual situation, choose the most suitable material. This will not only make the building more stable, but also save costs and speed up construction. Remember, don't buy it.
The difference between high-frequency welding thin-wall H-shaped steel and hot-rolled H-shaped steel
In this era of rapid economic development, H-beams have become the darling of builders. It can be divided into two types: welded H-shaped steel and hot-rolled H-shaped steel. Among them, welded H-shaped steel can be divided into high-frequency welded thin-wall H-shaped steel and submerged arc welded H-shaped steel. They have different characteristics.
