The FDZA CNC H-Beam Welding Production Line is an integrated automation system for H-beam, I-beam, and T-beam fabrication, covering material positioning, assembly, welding, and post-weld correction. It transforms raw steel plates into finished structural members with consistent weld quality, reducing production time by 40% vs. manual welding and eliminating labor-dependent variability.
• Dual-side synchronous welding reduces thermal distortion by 70% vs. single-side welding.
• Handles web heights from 300mm to 3000mm, flange widths from 200mm to 1250mm.
• Integrates assembly and welding into 3 steps (vs. 5 for traditional lines), cutting lead times.
• Real-time weld parameter monitoring ensures compliance with ASTM/AISC standards.
The defining feature of this welding line is its ability to perform simultaneous welding on both flanges of the H-beam using a four-head welding system—two heads per side. This symmetrical welding approach eliminates thermal distortion common in single-side welding processes, reducing post-weld correction requirements by up to 70%. The system utilizes a advanced double wire (AC+DC) welding process that creates stable molten pools, ensuring full penetration welds with minimal spatter and porosity.
The welding line handles a broad range of beam dimensions, with web heights from 300mm to 3000mm, flange widths from 200mm to 1250mm, and material thicknesses from 5mm to 50mm. Beam lengths can be processed up to 12 meters in standard configuration, with extended versions available for longer members. This versatility allows fabricators to produce everything from small secondary beams to large primary structural members using a single system.
The line features an innovative assembly-welding integration design that combines positioning and welding in a single station, eliminating the need for intermediate material handling. Precision servo-driven rollers position the web and flange plates with ±0.5mm alignment accuracy, while hydraulic clamping systems secure the components during welding. This integrated approach reduces process steps from five to three, cutting overall production time by approximately 40%.
An industrial-grade PLC system with custom H-beam welding software controls all line operations, offering intuitive programming through a 15-inch touchscreen interface. The system stores welding parameters for different material grades and thicknesses, ensuring consistent results across production runs. Real-time monitoring of welding current, voltage, and travel speed provides quality assurance, with automatic adjustments for variations in material fit-up. Post-weld correction is handled by an eccentric roller system that corrects angular deformation while the beam is still hot, improving accuracy and reducing energy consumption.
The primary application of the CNC H-beam Welding Line is in producing structural beams for high-rise buildings, industrial warehouses, and manufacturing facilities. The consistent weld quality and dimensional accuracy ensure these beams meet the strict structural requirements for commercial construction, supporting heavy loads over long spans.
In civil engineering, the line produces H-beams for bridge structures, overpasses, and transportation hubs. The system’s ability to produce large beams with precise welds is critical for these infrastructure applications, where structural integrity directly impacts public safety and project longevity.
The welding line supplies precision H-beams for crane structures, material handling equipment, and industrial machinery frames. The dimensional accuracy of the finished beams ensures proper alignment of moving parts and reduces wear on mechanical components.
For offshore platforms, wind turbine support structures, and power plant frameworks, the line produces H-beams capable of withstanding extreme environmental conditions. The high-quality welds and material integrity are essential for these energy sector applications, where maintenance is costly and structural failure has severe consequences.
The primary welding process is a double wire submerged arc welding (SAW) system using both AC and DC power sources. This configuration provides higher deposition rates (up to 15 kg/h per wire) and better gap-bridging ability compared to single wire systems. The line can be configured with additional gas metal arc welding (GMAW) stations for specialized applications if required.
The line achieves a welding speed of 0.5 to 3 m/min depending on material thickness and weld size. In a typical 8-hour shift, it can produce approximately 40–60 metric tons of finished H-beams, representing a 300% increase in productivity compared to manual welding operations.
The CNC system allows for quick changeovers between different beam profiles, with typical setup times ranging from 15 to 30 minutes for major size changes. This includes adjusting guide rollers, clamping systems, and welding parameters—all controlled through the HMI without manual mechanical adjustments.
The welding line is optimized for carbon structural steels (ASTM A36, S235) and high-strength low-alloy steels (ASTM A572, S355) commonly used in structural applications. With specialized parameters, it can also process weathering steels (ASTM A588) and quenched-and-tempered steels up to 690 MPa yield strength.
The system includes in-process monitoring of weld parameters with real-time data logging, ultrasonic testing capabilities for weld integrity verification, and dimensional measurement systems that check flange parallelism and web perpendicularity. All quality data can be stored and exported for compliance documentation and process improvement analysis.
