Zhouxiang Welding Robots Have Solved the Challenging Problem of Welding Large Transformer Oil Tanks.

Cantilever Welding Robot for Welding Large Oil Tanks

In the manufacturing system of large power transformers, the oil tank, as a core shell component, has its strength, sealing performance, and geometric accuracy directly determining the overall assembly quality and operational reliability of the equipment. Welding, as a critical process in oil tank manufacturing, has a decisive impact on the quality of the final product. However, the current domestic transformer oil tank manufacturing industry still widely uses manual welding and semi-automatic contour welding processes, with only a few companies attempting to introduce welding robots. The level of automated welding urgently needs to be improved.

Compared to traditional welding methods, robotic welding demonstrates significant advantages in terms of quality stability, production efficiency, and improved working conditions. As a national-level specialized and innovative "little giant" enterprise, Zhouxiang Company's intelligent cantilever welding robot solution provides an innovative answer for large oil tank welding. This solution, through its unique nine-axis cantilever structure design, utilizes three external axes for flexible movement, covering a working radius that can handle large workpieces up to 3.5 meters wide and 2.7 meters high, completely solving the problem of insufficient coverage of large oil tanks by traditional robots.

In terms of core technology, the robot is equipped with an advanced "teach-free programming system" and 3D vision seam tracking technology. It supports direct import of 3D models or generation of point cloud data through stereo camera scanning, enabling automatic and precise identification of weld seam positions and intelligent matching of welding process parameters. The welding accuracy reaches ±0.02 millimeters, and coupled with a real-time arc tracking system, it can dynamically correct minor deviations caused by thermal deformation. This transforms welding from a skill heavily reliant on the experience of skilled craftsmen into a stable and reliable standardized digital process, resulting in a revolutionary improvement in weld seam quality consistency.

Practical experience has shown that introducing Zhouxiang intelligent welding robots not only effectively alleviates the shortage of skilled welders but also helps companies build flexible production lines. For the "multi-variety, small-batch" production of oil tanks, the robots significantly improve production efficiency and resource utilization, playing a positive role in boosting enterprise capacity and opening up a new intelligent path for the high-quality development of the transformer oil tank manufacturing industry.
