CNGBS W-Series Modular
Cobot Welding Workstation

Designed for multi-variety, small-batch manufacturing and the shortage of skilled welders, the CNGBS W-Series modular welding workstation redefines welding automation. It combines collaborative robots, proven welding hardware, the Co-Pilot Tool intelligent programming device, a full-function welding process package and a teaching-free welding system into a fully modular, freely configurable intelligent welding platform. Based on unified interfaces and a shared attachment ecosystem, you can start from any core unit and combine configurations like building blocks — from desktop tables and mobile carts to positioners and long-seam gantries, plus the CWC13-CS66 portable cobot welding robot for true on-the-go welding.

Welding Supporting System

Software & Process Package

The shared software stack behind every W-Series workstation — from joystick programming to 3D vision teaching-free welding.

Full-function welding process package software

■ Full-function Welding Process Package

  • Function modules in free combination · mainstream welders adapt in one click · precise welding-parameter control · rich weave waveforms
  • Full coverage: straight welding, circular welding, mixed welding, contact seam finding, arc tracking and other advanced modules
  • Efficiency leap: graphical configuration generates programs in one click — programming efficiency doubled
  • No barrier: deploy advanced processes without professional code knowledge; covers MAG welding, laser welding, plasma cutting and more

■ Contact Seam Finding & Arc Tracking

  • Contact seam finding: detects actual workpiece position and attitude by physical contact before welding — immune to reflections, arc light and fumes; simply teach a datum point and the path is detected and compensated automatically
  • Arc tracking: monitors arc parameters in real time and dynamically compensates deviations in different directions — overcomes heat deformation and assembly errors; ideal for medium/thick plate, long seams and multi-layer welds, significantly cutting rework
Co-Pilot Tool intelligent programming device

■ Co-Pilot Tool — Welding Control in One Joystick

  • Handheld all-in-one control: independent handheld design, no tablet or teach pendant needed; joystick matches operator intuition with single-axis / blended modes and swappable translation / rotation coordinates that stay in sync with any robot mounting
  • Real-time status at a glance: indicator lights show communication status, program progress and wire feed/rewind state
  • Flexible connections: wrist-mounted follow mode, control-cabinet USB or 485 handheld connections for different station layouts
  • One-touch functions: custom buttons for saving waypoints, undo/reset, program start-stop and wire feed/rewind — no round trips to the host interface
Teaching-free welding system with 3D vision

■ Teaching-free Welding System

For frequent changeovers, time-consuming teaching and hiring difficulties, the teaching-free system fuses “3D vision + intelligent algorithms” into a closed loop from drawing to weld — mapping 3D models directly onto physical weld seams and minimizing reliance on programming experience.
