7-Axis Upright Rail-Mounted Robotic Welding Workstation
Gas-shielded robotic welding of H-section columns, roof beams and crane beams on a 12 m ground rail.
- Model
- HLZZHJ-R-QJLX-12
- Starting At
- From $139,000 USD
Inverted-mounted welding robot on a 12 m rail for improved torch access to open structural members.
Starting prices reflect base equipment configurations. Final pricing depends on system configuration, application requirements, shipping destination, installation, commissioning, training and project scope.

A seven-axis workstation in which the six-axis robot is mounted inverted above the workpiece and travels along a 12 m ground rail.
The inverted arrangement improves torch approach angles on open structural steel members while keeping the same welding, vision and control configuration as the upright station.
