Zhongtuo provides a fully automatic laser welded tube roll forming line that delivers high-precision, continuous tube manufacturing for industrial applications. This professional tube roll forming machine covers the entire production process from hydraulic decoiling, strip welding, roll forming, laser welding to fixed-length flying saw cutting. It ensures stable running, superior welding quality, and accurate tube cutting for all kinds of metal tube production projects.
Unlike traditional tube making equipment, our laser welded tube production line adopts advanced online laser welding technology and servo tracking cutting system. It effectively optimizes tube roundness, weld flatness and overall surface finish. Manufacturers widely use thisautomatic tube making machine for mass production of straight-seam welded tubes with consistent shapes and clean welding seams.
Zhongtuo’s laser welding galvanized steel fence tube roll forming line is purpose-built to fabricate high-quality 60×40 profile stalowe fence tubing. This integrated rollforming line tube handles galvanized steel strips efficiently while protecting the zinc coating during forming and laser welding. The production workflow combines decoiling, continuous roll forming, inline laser welding, straightening and flying saw cutting to deliver dimensionally consistent rectangular fence tubes. Optimized for mass production of security and garden fencing materials, the line generates tidy, low-defect weld seams without severe galvanization burnout. Operators gain reliable length accuracy and stable running speed. We customize the roller sets strictly according to 60×40 tube specifications, enabling manufacturers to produce uniform galvanized fence profiles with stable mechanical performance and attractive surface finish.
Key Advantages of Laser Welded Tube Roll Forming Line
Our metal tube roll forming line features high automation, stable welding quality and precise cutting performance. First, it realizes full-process automatic production from decoiling to finished tube output, saving labor costs and improving production continuity.
Second, the professional online laser welding technology with extrusion and scarfing treatment ensures flat, flawless and high-strength weld seams. Third, the servo flying saw non-stop cutting system guarantees high-precision fixed-length cutting without line shutdown.
In addition, we support flexible customization on machine layout, tube size and processing flow. Whether you need standard tube equipment or customized production lines, Zhongtuo can provide reliable solutions for your welded tube production line projects.
Complete One-Stop Production Workflow
This high-efficiency metal tube roll forming line supports fully automated continuous operation with zero-stop production. Every processing station connects tightly to ensure stable material feeding and uniform finished tube quality. The standard workflow is scientifically arranged to reduce production errors and improve overall capacity.
The full production flow includes: Decoiling → Strip End Shearing & Welding → Inline Punching → Roll Forming → Laser Welding → Tube Straightening → Flying Saw Cutting → Run-out Table. Each step undergoes precise parameter control to guarantee stable performance of the whole welded tube production line.
Core Equipment Configuration & Performance Features
Our industrial-grade laser welding tube machine adopts modular and heavy-duty structures to achieve long-term stable operation. Every functional unit targets practical production needs and improves the precision and durability of tube manufacturing.
First, the 3T+3T dual-station hydraulic decoiler offers stable steel coil unwinding with hydraulic expansion and wireless remote control. It maintains constant strip tension and greatly improves the feeding stability of the entire tube forming and welding machine.
Second, the strip end shearing and MIG/MAG butt welder automatically shears and joints steel strips. It realizes endless strip feeding and ensures continuous production for subsequent forming and laser welding procedures.
Third, the high-precision punching device installs inline before forming. Equipped with high wear-resistant Cr12MoV molds and 11KW power, it completes accurate hole punching according to customer profile requirements.
Fourth, the main roll forming machine adopts a cassette-type structure with 16 forming stations. The gearbox driving system ensures stable transmission, while the water cooling system effectively protects rollers during long-hour operation. The servo positioning adjustment supports fast size switching for different tube specifications.
Fifth, the 6KW online laser welding system serves as the core of the laser welded tube roll forming line. It achieves high-speed, continuous laser welding with 6-roller extrusion and external scarfing devices. The system perfectly removes welding burrs and produces ultra-smooth weld seams without deformation.
Sixth, the servo flying saw cutting system realizes non-stop tracking cutting. With a four-roll straightening device, it controls tube straightness and cutting length within ±1.0mm tolerance. This system greatly improves finished product qualification rate for mass tube production.
