The difference between steel rods and steel bars

The difference between steel rods and steel bars

21 May,2024

Differences between steel rods and steel bars in terms of material properties, manufacturing processes, application fields, etc. Prestressed steel rods are mainly used in situations where high strength and special mechanical properties are required, such as in prestressed concrete structures, while steel bars are widely used in ordinary building structures.

What are the welding methods of steel pipes?

Manual arc welding. This is a method in which the welding rod and steel pipe are melted by the high temperature generated by the arc, and then cooled and solidified to form a weld. It has simple equipment and flexible operation, and is suitable for welding steel pipes in various positions and thicknesses. Gas shielded welding. This method uses an inert gas (such as argon) or a reactive gas (such as carbon dioxide) to protect the welding area and prevent air intrusion and oxidation. The welding quality is good and the efficiency is high, and it is suitable for the welding of medium and thin wall steel pipes. Submerged arc welding. This is a method of welding by igniting an arc under a layer of flux. The welding speed is fast and the efficiency is high, but it is generally only suitable for welding steel pipes in horizontal positions or with small inclinations. Hot melt welding. Suitable for the installation of specific materials such as PPR pipes, using hot melt tools and cutting tools, as well as complete sets of integrated tools for welding. In addition, the welding methods of steel pipes include butt welding, socket welding, etc.
