Steel Processing Automation From Cutting to Welding Flow

2026-07-11

What is the automated route for steel processing?

The automated route for steel processing links digital detailing, CNC cutting, marking, assembly, welding, straightening, shot blasting, and traceability. Honglu’s route starts with more than 1,000 detailing engineers using Tekla Structures and continues into HOLU Technology equipment deployed across Honglu’s own factories.

Where does laser cutting fit in steel automation?

Laser cutting fits at the front of intelligent manufacturing steel because plate accuracy, beveling, marking, and nesting affect downstream operations. Honglu’s CNC fiber laser cutting machine HLMSF26030-20000W uses a 20,000 W Raycus MFMC-20000W source, 3D 5-axis Gangchun cutting head, LNC nesting/control software, and Mingtu MP380V profile-inspection sensor.

How does Honglu connect cutting data to component identity?

Honglu connects cutting data to component identity through its steel-structure cutting and marking method/system and CNC software stack. The relevant intellectual property includes invention patent CN202211192872.3 for steel-structure cutting and marking, invention patent CN202111056156.8 for BIM model management through mobile QR scanning, and software copyright No. 15064872 for Honglu Laser Steel CNC System Application Software.

  • Cutting and marking support component routing.
  • QR scanning supports BIM model management.
  • LNC nesting/control software supports laser processing.
  • Optional MES supports QR-code drawing retrieval.

Which equipment supports H-beam production after cutting?

H-beam production after cutting is supported by assembly, welding, and straightening machines already scaled inside Honglu factories. This route makes steel processing automation a connected factory flow rather than a single purchase.

Why does surface preparation belong in automation in the steel industry?

Surface preparation belongs in automation in the steel industry because blasting quality affects coating readiness, inspection flow, and repeatable fabrication output. Honglu uses Q1525-10 pass-through shot blasting machines with Sa2.5 surface preparation per GB/T 8923 for components up to 1500 x 2500 mm.

How does smart manufacturing control welding after material flow?

Smart manufacturing controls welding after material flow by using model import, seam extraction, process matching, trajectory planning, collision detection, and real-time seam tracking. Honglu’s automated welding systems use Megmeet Dex2 500MPR, laser sensing, and in-house controller software to keep cutting, fit-up, and welding decisions aligned.

  1. Import STEP, IGS, or IFC.
  2. Extract weld seams.
  3. Match parameters from the expert database.
  4. Plan trajectory.
  5. Run collision detection.
  6. Weld with seam tracking.

What proves factory-flow automation at Honglu scale?

Factory-flow automation is proven by Honglu’s capacity, workforce, plant footprint, and own-use equipment fleets. Honglu exceeds 5 million tons of annual steel-structure capacity, employs more than 20,000 registered frontline skilled technicians, centrally procures raw steel, and maintains a year-round stockpile of at least 300,000 tons including Q390, Q420, and Q460.
