Drawing Import Welding Programming for Steel Robots

2026-07-21

How does drawing import welding reduce manual teaching?

Drawing import welding reduces manual teaching by converting STEP, IGS, and IFC geometry into weld-seam extraction, parameter matching, trajectory planning, collision detection, and robot execution. Honglu’s model-driven welding software runs on a PC and controls equipment remotely over TCP/IP.

IGSSeam extraction
IFCModel-driven welding
Tekla Structures model baseDetailing workflow
Collision detectionFull-path checking

The HLZZHJ-R-QJLX-12 floor-mounted rail-guided workstation supports model import plus one-click start.

Which welding drawings belong in structural-steel robot programming?

Structural-steel robot programming belongs with H-columns, roof beams, crane beams, box columns, cross-shaped columns, and bridge unit plates. Honglu maps welding drawings to exact workstation classes instead of treating every weld detail as a single automation problem.

This equipment mapping gives weld drawings and welding blueprints examples a manufacturing route.

When does blind welding replace imported drawings?

Blind welding replaces imported drawings when the tack-welded workpiece has no usable model, arrives as a non-standard component, or requires repair programming without drawing data. Honglu’s HLDZXBHJ-R-QJLX-14-6 inverted cantilever workstation scans the workpiece, reverse-models the point cloud, and auto-generates the weld program.

What quality language should welding blueprints preserve?

Welding blueprints should preserve WPQ/WPS, full-penetration weld, Grade 1 weld, fillet weld, root pass, filling pass, cover pass, NDT, UT, and ISO 3834 language. Honglu connects these terms to robot process control and export certification.

Blueprint termProduction meaning
Full-penetration weldStructural weld requirement
Root passFirst pass sequence
Filling passBuild-up sequence
Cover passFinal pass sequence
NDT / UTInspection language
EN 1090-1 / EN 1090-2EU steel-structure context

How does the process library turn weld drawings into execution?

The process library turns weld drawings into execution by matching geometry to verified welding functions from Honglu factory data. The database is derived from millions of tons of real production data and tens of millions of verified welds.

Library functionHonglu-supported capability
DC gas-shielded arcProcess option
Pulsed weldingProcess option
Oscillation patternsSinusoidal, triangular, arc, V, pendulum
Laser non-contact positioningSeam location
Arc trackingIn-process correction
Arc-break restartRecovery function

The welding process library robotic automation article gives the software background.

Why does Honglu use Tekla-based detailing before robot welding?

Honglu uses Tekla-based detailing before robot welding because more than 1,000 dedicated detailing engineers model every project in Tekla Structures. The model discipline connects engineering drawings, QR-code retrieval, MES options, and robot path generation inside the same manufacturer-operator workflow.
