Welding Section

The welding section represents the critical joining point in every ERW tube mill line, where precisely formed strip edges are heated and forged together to create a strong, continuous weld seam. SRET designs and manufactures advanced high-frequency welding systems that achieve excellent weld penetration and metallurgical bonding without filler material, producing tubes suitable for demanding structural, mechanical and pressure applications. Our engineering team configures each welding station to match your specific tube diameter, wall thickness and production speed requirements. Key components include squeeze rolls for precise edge alignment, induction or contact welding heads for efficient heating, and integrated monitoring systems to maintain optimal welding parameters. By controlling current frequency, power delivery and squeeze pressure, SRET welding sections help you achieve consistent seam quality, minimal heat-affected zones and high production efficiency across your entire ERW tube mill operation.
