01 / PRODUCT OVERVIEW

How this equipment works.

A cantilever workstation combines a suspended six-axis welding robot with two external motion axes. The moving cantilever extends the robot’s working area across the planned cell and leaves the workpiece arrangement to be designed around the fabrication task.

After the parts are tack-welded and positioned, global scanning identifies the assemblies and close-range vision refines the weld coordinates. The system combines these coordinates with welding-process data to generate the program. A water-cooled torch and automatic cleaning unit support the welding cycle.

Before choosing a configuration

Plate height, spacing and included angle affect scanning and torch access. Submit typical sections and fixture heights to verify the actual envelope and identify welds that need repositioning or a separate operation.

03 / PROCESS & CONFIGURATION

Designed for the task.

Global scanning supports recognition of multiple tack-welded parts.
Close-range vision refines weld positioning.
Automatic program generation from welding coordinates and process data.
Water-cooled torch and automatic cleaning configuration.

TECHNICAL OVERVIEW

Key specifications

8-axis cantilever welding specifications
Workstation axes	6 robot axes + 2 external axes
Reference rail length	12 m
Robot reach	2014 mm
Robot payload	6 kg
Robot repeatability	±0.08 mm

Configuration reference: HNGJ Global. Workpiece envelope is project-specific. Product image is a configuration illustration. 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.

This is a separate reference configuration from the supplementary sheet. Rail length and robot reach may differ from the catalog configuration above; the final equipment list and working envelope are confirmed in the technical agreement.

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

Plan checks for cantilever motion, camera calibration, torch cooling and automatic cleaning. Training can cover part recognition, weld selection, process adjustment and safe restart after a fault.

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.
