Factory Robots for Steel-Structure Manufacturing at Honglu Scale

2026-07-23

What Makes Factory Robots Relevant To Steel Structures?

Factory robots become relevant to steel structures when they weld, cut, inspect, track, and repeat production tasks inside a high-volume manufacturer-operator environment. Honglu Group operates as Anhui Honglu Steel Construction (Group) Co., Ltd., stock code Shenzhen 002541, and HOLU Technology is its robotics and smart-manufacturing arm. The core proof point is direct operation: Honglu runs 2,000+ welding robots 24/7 in its own plants, not as a generic integrator demo. The company has annual steel-structure capacity exceeding 5 million tons and exports to more than 30 countries and regions.

Which Robot Categories Belong In The Factory Fleet?

Honglu’s factory robot fleet covers rail-guided welding, submerged-arc welding, inverted cantilever welding, eight-axis heavy-part welding, compact cobot welding, and CNC fiber laser cutting. The selection path starts from workpiece geometry and weld type.

CategoryHonglu modelVerified role
Rail-guided weldingHLZZHJ-R-QJLX-12H-columns, roof beams, crane beams
SAW weldingHLZZHJ-R-QJLX-12MBox columns, H-beams, thick-plate full penetration
Blind weldingHLDZXBHJ-R-QJLX-14-6Bridge unit plates and no-drawing parts
Cobot weldingHLQQHJ-R-SR3C-705Large irregular components

The full product route is listed in Honglu’s automation product catalogue.

How Do Robots Work Without New Manual Programming?

Robots work without new manual programming by using model-driven welding or model-free reverse modeling. In model-driven welding, Honglu imports STEP, IGS, or IFC geometry, then software parses the workpiece, extracts seams, matches process parameters, plans trajectory, checks full-path collision, and executes welding. In model-free welding, a large-scene global camera scans the tack-welded component, reverse-models the point cloud, and generates the weld program without drawings. The inverted cantilever robot welding workstation exists for bridge plates, non-standard incoming material, repair parts, and overseas workpieces.

What Controller Architecture Separates Manufacturer Robots From Integration Projects?

Controller ownership separates Honglu factory robots from integration projects because HOLU Technology develops the operating system, robot controller, point-cloud algorithms, and vision system in house. The control software runs on a PC and operates equipment remotely over TCP/IP. This architecture supports model import, line-scan sensing, collision detection, seam tracking, MES options, QR-code drawing retrieval, production statistics, and a DeepSeek-powered welding expert experience base. Support terms are also defined: 12-month free warranty, 1-hour response to written fault notice, on-site service within 24 h, and a 24/7 technical hotline.

Which Factory Robots Anchor Heavy-Part Production?

Heavy-part production is anchored by the Honglu Eight-Axis Cantilever Intelligent Workstation, the SAW workstation, and the CNC fiber laser cutting machine. The eight-axis HLR6-2000D system uses a 14 m X-axis rail, 2.5 m Y-axis, and two additional axes. Its footprint is 14,000 x 6,500 mm, maximum workpiece is 12,500 x 3,800 x 500 mm, load is 500 kg, positioning accuracy is +/-0.5 mm static and dynamic, and maximum travel speed is 0.3 m/s. The Megmeet Dex2 500MPR and TRM TRM602WHD torch support heavy structural welding workflows.

How Should Factory Robot Buyers Read Market News?

Factory robot buyers should read robotics manufacturing news through verified production data, not broad automation claims. Honglu’s future of automated welding cluster explains the welding automation direction, while Honglu smart manufacturing news connects factory upgrades with orders and production. The factual anchors remain measurable: more than 20,000 registered frontline skilled technicians, more than 1,000 detailing engineers, centralized raw-steel procurement, year-round stockpile of at least 300,000 tons, and certification coverage including AISC, EN 1090, ISO 3834, UKCA, GOST-R, CIDB, CPA, and IBS.
