1200mm Longitudinal Seam Welding Machine Automatic Straight Seam Welder

The 1200mm longitudinal seam welding machine is specialized automatic equipment designed for straight butt seam welding. It features a pneumatic keyboard clamping structure to securely fix cylindrical shells or flat plates. The servo torch carriage ensures stable travel for high-quality longitudinal welds. Compatible with TIG, MIG, and MAG welding sources, this machine is widely used in stainless steel tank, duct, and small pressure vessel shell production. It can integrate with welding rotators and positioners to create fully automated production lines. All machines are manufactured in our own factory, with non-standard modifications available to meet specific workshop requirements.
