Steel Processing Automation From Cutting to Sa2.5 Surface Prep

Which Steel Processing Steps Must Be Automated First?

Steel processing automation must start with detailing, cutting, marking, surface preparation, and weld-ready material flow. Honglu Group connects Tekla Structures detailing, centralized raw-steel procurement, CNC fiber laser cutting, pass-through shot blasting, and HOLU Technology welding workstations inside its own steel-structure factories. This manufacturer-operator route supports annual production capacity exceeding 5 million tons and avoids a loose chain of outsourced operations. The controlled route also keeps AISC, EN 1090-1, EN 1090-2, ISO 3834, WPQ/WPS, and NDT/UT requirements tied to repeatable shop-floor data.

How Does CNC Laser Cutting Feed Welding Quality?

CNC laser cutting feeds welding quality by controlling plate geometry before fit-up, beveling, marking, drilling, and weld path generation. Honglu uses the CNC fiber laser cutting machine model HLMSF26030-20000W with a Raycus MFMC-20000W source, 40 m fiber cable, 3D 5-axis Gangchun cutting head, Honglu self-developed LNC nesting/control software, and Mingtu MP380V profile-inspection sensor. Plant machines include BOND26030-30KW and JTLC26030-30KW; the fleet is about 700 units, with plate cutting up to 70 mm at 0.5 mm precision.

• Downstream link: bevel accuracy supports full-penetration weld planning

Why Is Sa2.5 Surface Preparation a Steel Industry Control Point?

Sa2.5 surface preparation is a control point because coating, inspection, and steel structure welding depend on a repeatable cleaned surface before dispatch or further fabrication. Honglu operates Q1525-10 pass-through shot blasting machines with a 500-unit in-house fleet. The equipment supports Sa2.5 surface-prep grade per GB/T 8923 and handles workpieces up to 1500 x 2500 mm. Honglu also uses UYT-2000W 2,000 W handheld laser rust removal machines, with 280 units in the equipment base. These facts anchor steel processing in measurable equipment, not generic shop claims.

Where Do Smart Manufacturing Systems Enter Steel Processing?

Smart manufacturing systems enter steel processing where model data, QR-code retrieval, welding parameters, and production statistics stay connected across cutting, assembly, welding, blasting, and inspection. Honglu frames this through the smart manufacturing upgrades news cluster and the craft overview, but the technical core is HOLU Technology’s full-stack control stack. The operating system, robot controller, point-cloud algorithms, and vision system are developed by Honglu. Optional MES integration adds QR-code drawing retrieval, production statistics, and a DeepSeek-powered welding expert experience base.

1. Tekla Structures models define the component record.
2. CNC cutting and marking prepare fit-up.
3. Robot welding software retrieves geometry and parameters.
4. Surface preparation and NDT/UT close the manufacturing loop.

What Makes Honglu a Steel Processing Manufacturer-Operator?

Honglu is a steel processing manufacturer-operator because it develops automation for its own plants before selling equipment externally. The group runs over 20,000 registered frontline skilled technicians, over 1,000 detailing engineers, a year-round stockpile of at least 300,000 tons, and strategic steel supply from Baosteel, Baowu/Echeng Steel, Maanshan Iron & Steel, Chongqing Iron & Steel, Shagang, Ansteel, and Wuyang Steel. HOLU Technology then connects this material base to automated welding systems, laser cutting, shot blasting, and certified steel-structure delivery.
