- High-Frequency Electric Resistance Welding (ERW) In this method, electrical currents are passed through the edges of the metal strips to heat them, allowing them to fuse together under pressure. This technique is highly efficient and produces a continuous weld along the length of the pipe.
3. Control Systems Modern steel bar straightening machines are equipped with advanced control systems that monitor parameters such as pressure, speed, and alignment. These systems help maintain quality and consistency in the straightening process. Operators can adjust settings as necessary to accommodate varying bar diameters and materials.
