ZFH1000 Straight Seam Welding Machine | Automatic Longitudinal Seam Welder for Stainless Steel Cylinder Tank Barrel
The ZFH1000 straight seam welding machine is professional automatic longitudinal welding equipment specially designed for cylindrical blanks, metal barrels, and flat sheet butt welding. It features a cantilever thick steel frame with stress relief treatment, equipped with pneumatic key pressing fixture and copper lining back gas protection mandrel, achieving flat, uniform longitudinal welds without secondary polishing.
This machine supports TIG argon arc, MIG, and plasma welding processes, making it suitable for thin stainless steel, carbon steel, copper, and aluminum workpieces. With an effective welding length of 1000mm, it is widely used in water tank, milk can, fire extinguisher cylinder, and heat exchanger tube manufacturing.

Core Advantages
Cantilever Deformation-Free Frame: Whole thick steel plate welding structure with aging treatment ensures long-term continuous operation without bending deformation.
Adjustable Pneumatic Key Press Clamping: Even pressing force along welding seam with adjustable key spacing effectively restrains thermal deformation during welding.
Copper Mandrel Back Gas Protection: Enables single-side welding with double forming, producing smooth inner welds without oxidation and improving product tightness.
Stable Servo Welding Torch Travel: Precision linear guide with rack drive ensures uniform welding speed and consistent weld bead appearance.
Integrated Cable Drag Chain Design: All air pipes and wires hidden inside drag chain prevent breakage and facilitate neat, easy maintenance.
Multi-Material Compatibility: Compatible with stainless steel, carbon steel, copper, and aluminum thin plate cylinder workpieces with customizable mandrel sizes.
Application Range
Stainless steel water tank, storage barrel, heat exchanger cylinder production
