The ZF1200 longitudinal straight seam welding machine is designed for 1200 mm medium long seam fabrication. Its rigid cantilever frame and full-length pressing system effectively reduce seam offset, workpiece deviation, and thermal deformation. Ideal for tank, barrel, and thin-wall tubular parts manufacturing, this machine enables one-side welding with double-side forming to significantly increase finished product rates.
