7-axis rail-guided welding

A six-axis robot on a floor-mounted travel rail brings a wider working range to structural-steel welding. Suitable applications include H-columns, roof beams, crane girders and brackets.

01 / PRODUCT OVERVIEW

How this equipment works.

A six-axis welding robot mounted on a floor travel axis extends the reachable welding area along the component. The arrangement suits long, relatively open steel members whose welds can be accessed from the planned rail position.

Import STEP or IFC models, or reconstruct a tack-welded part from a 3D scan. The workflow extracts welds, matches process data and checks the planned path for collisions before precise seam scanning and welding. Part preparation and scan confirmation remain operator tasks.

02 / COMPONENT TYPES

Find the fit for your parts.

H-beams, H-section columns, roof beams and crane girders

Curved beams with accessible welds

Cross-shaped columns

Box columns at accessible assembly stages

Steel stairs

Purlin support plates, brackets and corbels

Before choosing a configuration

Review rail-side access, workpiece width, stiffener spacing, torch clearance and weld position. A long rail does not make every surface accessible in one setup.

03 / PROCESS & CONFIGURATION

Designed for the task.

Import STEP / IFC models or reconstruct parts from a 3D scan.
Automatic seam extraction, path planning and collision checks.
Laser localization and precision seam scanning.
Multilayer, multipass welding for suitable thick-plate joints.

TECHNICAL OVERVIEW

Key specifications

7-axis rail-guided welding specifications
Workstation axes	6 robot axes + 1 travel axis
Reference rail length	12 m
Workpiece width	≤1.4 m
Robot reach	2014 mm
Robot repeatability	±0.08 mm

Configuration reference: HNGJ Global. Parameters apply to the referenced configuration. Final scope is confirmed in the technical agreement. Robot-only figures are identified separately.

APPLICATION & PROCESS

Confirm the welding fit.

Shared process guidance for the seven- and eight-axis GMAW workstations.

Workpiece material	Carbon steel and low-alloy steel; stainless steel requires application validation.
Welding method	Gas metal arc welding (GMAW)
Reference plate thickness	5–30 mm
Welding positions	PA flat, PB horizontal-vertical fillet, PG vertical-down
Shielding gas options	80% Ar + 20% CO₂; 100% CO₂; 95% Ar + 5% O₂
Solid wire diameter	Ø1.0 / Ø1.2 / Ø1.6 mm
Flux-cored wire diameter	Ø1.2 mm

Gas and wire are selected for the material and qualified welding procedure. Stainless steel suitability requires validation of surface reflection, scanning and arc tracking.

Access matters as much as reach.

Flat-web components must allow camera scanning and torch approach. Reference rib clearances are 150 mm for flat welding and 450 mm for vertical welding, subject to torch geometry and surrounding plate height.

PREPARE YOUR ENQUIRY

A useful brief gets a clearer proposal.

Send material grade and thickness, maximum part dimensions and weight, joint or cutting details, batch size, target output and the installation country. Describe the current process and the bottleneck you want to resolve.

04 / AFTER-SALES SUPPORT

Support throughout operation.

Build a service plan around your equipment, operators and installation location. The following items can be included in the agreed project scope.

Installation & commissioning

Agree checks for the robot installation, external axes where fitted, fixtures, power, gas and extraction. Commissioning reviews coordinate references and sample welds against the agreed process.

Operator training

Training can include job preparation, the supported programming or scanning method, process selection, weld inspection and routine restart procedures.

Care & maintenance

Robot and rail checks cover reference positions, lubrication, torch cleaning, wire feeding and camera calibration. Operator support should include model import, scan review and recovery from interrupted jobs.

Troubleshooting & spare parts

Share the equipment model, fault code, operating conditions and relevant photos when requesting support. Diagnosis, replacement parts and any on-site visit are coordinated for the installed configuration and project location.

Warranty & service arrangements

Warranty duration, consumable coverage, software support and response arrangements are confirmed in the project agreement. Overseas on-site work, travel costs and parts delivery are agreed for the destination.
