Zhouxiang T-bar production line: driving the transformation and upgrading of smart shipyards
Nov 06, 2026
Zhouxiang T-Bar Production Line
To meet the demand for large-scale T-bar fabrication in the shipbuilding and steel structure industries, Zhouxiang has developed a fully automated T-Bar Production Line that integrates the entire manufacturing process, from raw panel and web plate loading to finished product output, into a complete, closed-loop production system.
The production line is equipped with panel and web plate loading systems, a panel centering system, a web plate positioning device, an automatic web plate grinding machine, an automatic panel grinding and chamfering machine, a T-Bar assembly machine, a T-Bar Multi-Head Gantry Welding Machine, and a hydraulic T-Bar straightening machine. It also features supporting roller conveyors and workpiece turning devices, with a transverse transfer system available as an optional configuration.
T-Bar Automatic Grinding and Chamfering Machine
The web plates and panels are lifted by an overhead crane and placed at the loading stations, then conveyed along the roller conveyor to the panel centering and web plate positioning systems for alignment. Once the plate reference edges are properly aligned, the workpieces continue moving forward and enter the automatic web plate grinding machine and the automatic panel grinding and chamfering machine respectively, where surface grinding and panel edge chamfering operations are completed.
T-Bar Assembly Machine
The panel to be assembled is lifted onto the input roller conveyor, and the web plate is rotated 90° and placed onto the panel. The centering unit ensures precise alignment of the web plate with the panel, including flush alignment of their ends. After positioning and calibration, the automatic coordinated tack welding unit performs high-precision fit-up and tack welding to ensure perpendicularity and assembly accuracy. The PLC then controls automatic intermittent tack welding using the gas metal arc welding (GMAW) process. Once tack welding is completed, the workpiece is conveyed to the transverse transfer system.
T-Bar Multi-Head Gantry Welding Machine
After assembly and tack welding, the T-bar workpieces are conveyed via roller conveyors and transverse transfer mechanisms to the buffer storage rack. They are then lifted onto the welding clamping platform. Once the clamping device automatically positions and secures the workpieces, the multi-electrode gantry welding system performs synchronized welding.
Upon completion of welding, the clamping device is released, and the anti-toppling safety device provides effective protection to prevent the workpieces from tipping over or colliding.
T-Bar Hydraulic Straightening Machine
After the T-bar workpiece is lifted into the straightening station, it is fed into the main machine for automatic straightening. The floating roller conveyor automatically adjusts its height to accommodate the workpiece and ensure accurate positioning, efficiently correcting deformation caused by welding. Once straightening is complete, the finished T-bar is automatically discharged via the output roller conveyor.
Zhouxiang’s T-Bar Production Line integrates the entire manufacturing process, covering grinding, assembly, welding, and straightening. While ensuring consistent product quality, the production line reduces processing time and labor requirements, helping traditional shipyards accelerate their transition toward smart shipyard operations.
