Heavy Duty Laser Welded Pipe Mill Automatic High Performance Stainless Steel Tube Production Line for Engineering
Dongguang Hengfu Roll Forming Machine Co., Ltd. introduces a premium Laser Welded Pipe Production Line designed to meet the highest industry standards for precision, efficiency, and durability. This state-of-the-art solution integrates advanced roll forming technology with professional laser welding, engineered for seamless mass production of high-grade metal pipes. Backed by Hengfu's decades of manufacturing expertise and strict quality control, this line delivers consistent performance and reliable results, making it the backbone of any modern pipe manufacturing facility.
The production line operates on a fully automated, high-efficiency workflow: decoiling → precision roll forming → laser welding → straightening → non-stop cutting. Specifically configured for 0.6mm galvanized steel strips, the system ensures smooth material transition, uniform profiling, and strong, defect-free welds. Every stage is optimized to minimize material waste and ensure that finished pipes exhibit strict dimensional accuracy, excellent straightness, and a superior surface finish—critical for construction, engineering, and manufacturing applications.
At the heart of the system lies a robust 30mm thick CNC-machined gantry frame that guarantees exceptional stability under continuous high-speed operation. The forming section comprises 55 precision stations, fitted with Cr12 mold steel rollers (HRC 55-58) and 45# steel shafts (Φ60mm). Powered by four 5.5KW motors and equipped with premium Harbin bearings, the machine delivers smooth, low-vibration operation with long service life. Production speed is fully adjustable from 1-15m/min via PLC inverter control, offering flexibility to match varying order requirements.
The uncoiling unit features a heavy-duty, integrated tension system with a 2.0-ton load capacity, accommodating strip widths up to 400mm and coil inner diameters of Φ500mm. The Φ80mm solid main shaft and manual tensioning mechanism ensure stable, reliable uncoiling, providing a consistent material feed that is essential for maintaining high forming and welding precision.
Fitted with a high-performance 3KW laser welding system and an intuitive PLC touch-screen control interface, this line ensures superior welding quality and user-friendly operation. Every component is selected for reliability, and the entire system undergoes rigorous testing by Dongguang Hengfu Roll Forming Machine Co., Ltd. before shipment. The result is a production solution that delivers low maintenance, high uptime, and outstanding cost-effectiveness—ideal for manufacturers aiming to elevate productivity and product quality.

Frequently Asked Questions
Is there a leveling device at the material inlet?
It is equipped with a set of leveling rollers to ensure flat feeding and prevent waves or distortion in the sheet material.
Is the electrical system susceptible to moisture damage?
The electrical cabinet features a dust-proof and moisture-resistant design, allowing it to operate normally even within a simple outdoor shelter.
Will the machine scratch the surface coating of the color-coated steel sheets during production?
With precision-ground and polished rollers, combined with a properly designed forming process, the machine will not scratch the sheet surface under normal operating conditions.
Can the machine produce stainless steel sheets? What are the requirements for the equipment?
Yes, it can; however, it requires reinforcing the forming frames, increasing the hardness of the rollers, and adjusting the forming process.
