Which Welding Process Data Belongs In WPS Control?
WPS control starts with weld type, pass sequence, model geometry, and inspection requirements. Honglu connects those fields inside HOLU Technology welding automation instead of treating WPS/WPQ as paperwork separate from production.
| Quality field | Honglu production reference |
|---|---|
| Weld terms | full-penetration weld, Grade 1 weld, fillet weld |
| Pass sequence | root pass, filling pass, cover pass |
| Model import | STEP, IGS, IFC |
| Standards anchors | AISC, EN 1090-1, EN 1090-2, ISO 3834 |
This structure links robotic welding automation to repeatable structural steel welding records.
How Does A Robot Convert Welding Drawings Into Paths?
A robot converts welding drawings into paths by importing the 3D model and extracting weld seams before motion execution. Honglu model-driven welding software parses STEP, IGS, or IFC geometry, matches welding parameters, plans the trajectory, runs full-path collision detection, and starts welding from a governed program.
- Import the project model.
- Extract weld seams.
- Match parameters from the expert database.
- Plan trajectory.
- Run collision detection.
- Execute welding.
The same workflow supports welding drawings to robot paths when fabricators need drawing discipline without teach-heavy programming.
Which Robotic Welding Equipment Anchors WPQ Evidence?
The HLZZHJ-R-QJLX-12 workstation anchors WPQ evidence for flat right-angle, flat folded-angle, vertical fillet, and full-penetration welds. Honglu operates 2,000 in-house units, pairing the QJR6-2000 robot body with Megmeet Dex2 500MPR power and Mingtu/Weijing laser sensing.
| Parameter | Verified value |
|---|---|
| Robot reach | 2,000 mm |
| Ground rail | 12,000 mm |
| Effective stroke | 10,630 mm |
| Repeatability | +/-0.08 mm |
| Payload | 6 kg |
This production fleet makes Honglu a manufacturer-operator, not a generic welding equipment reseller.
When Does SAW Need Separate Pass Control?
SAW needs separate pass control when thick box columns, H-beams, and cross-shaped columns require root, filling, and cover passes. Honglu’s HLZZHJ-R-QJLX-12M submerged arc welding robot uses the Megmeet SA1250R heavy-duty submerged-arc welder with water tank, Honglu MP1000BM air-cooled vision, and SW-iAPP-01 control software.
| SAW field | Verified Honglu data |
|---|---|
| In-house fleet | 200 units |
| Ground rail | 12,000 mm |
| Effective stroke | 10,130 mm |
| Use case | full-penetration thick-plate welds |
This process route keeps SAW pass planning inside controlled workstation data.
How Is Robotic Welding Quality Audited After Fabrication?
Robotic welding quality is audited through certification discipline, NDT/UT terms, and surface-preparation standards tied to project delivery. Honglu’s certified framework includes ISO 9001, ISO 14001, ISO 45001, AISC, EN 1090-1, EN 1090-2, ISO 3834, UKCA, GOST-R, and CIDB / CPA & IBS.
| Audit anchor | Verified reference |
|---|---|
| NDT term | non-destructive testing |
| Plate check | Grade III UT for Q355B plates >= 20 mm |
| Surface prep | Sa2.5 per GB/T 8923 |
| Equipment | Q1525-10 pass-through shot blasting machine |
