- 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.
One of the key advantages of using a square pipe roll forming machine is its high level of automation
. Modern machines are equipped with computer numerical control (CNC) systems that enhance precision and repeatability. Operators can input specific measurements and parameters, and the machine will automatically adjust its settings to accommodate different sizes and shapes of square pipes.
