Product Features
Integrated Production Line
Integrates and synchronizes six key processes-uncoiling, leveling, roll forming, laser welding, sizing, and cut-to-length-eliminating the need for intermediate transfers. The entire line operates with synchronized timing, enabling continuous, automated production.
01
Advanced Laser Welding
Utilizes a fiber laser welding system with adjustable power output ranging from 1.5 kW to 3 kW. It produces narrow, uniform weld seams with a heat-affected zone (HAZ) of ≤0.5 mm, resulting in no visible discoloration on the tube surface after welding.
02
Precision Engineering
The forming rollers undergo precision CNC grinding and are constructed from quenched Cr12MoV steel (hardness: HRC 58–62). This ensures a welded tube outer diameter accuracy of ±0.3 mm and a straightness tolerance of ≤1 mm/m.
03
Hydraulic Cutting System
Features an on-line flying saw system that tracks and cuts the tube while in motion; the saw blade moves in perfect synchronization with the tube. This produces square, burr-free cuts with a length tolerance of ±1.5 mm and an end-face perpendicularity of ≤0.5 mm.
04
Robust and Durable
The machine frame is constructed from welded and tempered Q345B structural steel, while the forming rollers and drive shafts are made from hardened materials. The entire machine is designed for a service life of ≥10 years, capable of sustaining continuous 24-hour operation.
05
Application Scenarios
Construction Industry
Creates structural tubing for building frames, scaffolding, and support structures.
01
Manufacturing Sector
Produces square tubes for furniture, equipment frames, and material handling systems.
02
Automotive Industry
Manufactures rectangular tubes for chassis components and vehicle frames.
03
Infrastructure Projects
Provides tubular components for bridges, signposts, and fencing systems.
04
Metal Fabrication
Supplies custom square tubes for architectural and decorative applications.
05
Advantages
Economical and Efficient Solution
Eliminates the need for pre-slitting or cutting; coil stock is directly formed and welded, significantly improving material utilization. Compared to traditional processes, this method reduces scrap and edge waste by approximately 30%.
High-Efficiency Production
Continuous High-Speed Output:Production speeds reach up to 12 meters per minute. Based on standard pipe diameters, the output per single shift is approximately 2,000 meters, enabling large-scale, continuous operations.
Flexible Customization
Rapid Specification Switching:By simply replacing a few forming rollers and making minor adjustments to welding parameters, specification changes-including pipe diameter (e.g., round pipes from φ20 to φ80 mm) and wall thickness-can be completed within just 30 minutes.
Superior Welding Quality
Leverages fiber laser welding to produce narrow, uniform seams (with a penetration depth of 0.5–0.8 mm) and a minimal heat-affected zone. The resulting tube surface is smooth and free of visible discoloration, eliminating the need for secondary grinding or finishing.
Comprehensive Support
We provide a 12-month warranty. Our engineers can offer remote guidance for installation and commissioning, and we arrange 1–2 days of on-site or video-based training to ensure operators become proficient in using the equipment.
After-Sales Service
Installation and Commissioning
The equipment is supplied with complete foundation drawings, electrical wiring diagrams, and operation manuals. Wiring can be completed simply with the assistance of the client's electrician. Our engineers can provide real-time guidance on installation and initial commissioning via video link, eliminating the need to wait for an on-site visit.
Operator Training
Following equipment delivery, we provide 2–3 days of online training covering roll adjustments for product size changes, welding power settings, weld quality control, and daily inspection procedures.
Technical Support Response
Should any issues arise during equipment operation, clients may contact our technical department via telephone or instant messaging. We will provide a resolution plan within 4 hours on business days; inquiries received on holidays will be addressed on the next business day.
Spare Parts Supply
We maintain a safety stock of consumable parts-including forming rolls, sizing rolls, welder ferrite rods, and saw blades-that are prone to wear. Orders for spare parts are shipped within 48 hours of placement; we also provide a comprehensive spare parts list and information on local procurement alternatives for the client's emergency reference.
