Robot automatic loading and unloading and visual positioning

The six-axis robot grabs the pipeline workpiece and feeds it to the laser tooling. It scans the position of the pipe joint with 2D vision and corrects the laser welding trajectory in real time. Slight deviations in the placement of the workpiece do not affect the welding quality, greatly reducing the tooling processing accuracy requirements and reducing tooling replacement costs.

Fiber laser precision welding function

The laser outputs stable energy and optimizes the welding waveform for aluminum and stainless steel pipelines. The weld penetration is uniform and there are no empty welds, missing welds, or penetration holes. The welding parameters are regulated in a real-time closed-loop, and the power and speed abnormality are automatically shut down and alarmed to eliminate batch welding defects.

Weld AI visual defect detection

After welding, the high-definition camera scans the entire weld, and the AI algorithm identifies pores, cracks, lack of fusion, and welding deviation defects, automatically marks the defect location and retains the image, automatically diverts defective workpieces for repair, and intercepts welding sealing risks in advance.

Online air tightness leak detection after welding

Qualified workpieces are directly transferred to the vacuum leak detection station to detect weld micro-leakage and detect welding defects and pipeline sealing defects at once, eliminating the need for secondary transfer inspection and reducing the production cycle.

Digital traceability management of welding process

Each workpiece is bound with a barcode, and the laser power, welding time, weld defect determination, and leakage detection values are all uploaded to MES to completely record the process parameters of the entire welding process. The OEM can trace the source of pipeline welding quality and meet the IATF16949 control standard for automotive parts.

Commercial value: The defective pipe welding leakage rate has been reduced by 96%, manual weld visual inspection positions have been eliminated, and the smoke purification system has avoided environmental penalties; laser adaptive positioning has reduced the cost of tooling customization by 40%, and a single production line can produce 200,000 sets of welded pipelines annually.
