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.

• Upgraded 1200 mm welding stroke accommodates medium to large cylinder parts, eliminating the need for secondary re-welding
• Stress-relieved heavy-duty integral frame ensures stable long-run production with consistent welding accuracy
• Full-section pneumatic piano key pressing prevents sheet bounce, gaps, and wrinkling during high-speed welding
• Water-cooled copper mandrel with optional back-side gas shielding minimizes heat deformation for smooth weld appearance
• PLC touch screen control supports parameter saving and quick recipe switching for flexible batch production setup

• Designed for cylindrical and open shell workpieces, ideal for tank and pressure vessel component manufacturing
• Works with carbon steel, stainless steel, and aluminum alloy, compatible with TIG, MIG, MAG, and Plasma welding sources
• Processes material thickness from 0.5 mm to 4.0 mm, covering thin sheet and medium plate welding requirements
• Supports fine welding and high-volume production, adaptable for trial orders and assembly line manufacturing
• Minimum inner diameter of workpiece reaches 120 mm, satisfying various cylinder dimension demands
• 

• Cantilever layout simplifies loading and unloading, reducing workpiece positioning time
• High-precision rack and pinion drive with stepless welding speed ensures straight and uniform weld seams
• Multi-directional torch fine-tuning corrects assembly errors and improves product yield
• Foot switch auto cycle control reduces manual operation errors and labor intensity
• Modular construction facilitates easy inspection, maintenance, and component replacement
