AI Technical Summary

⚠Technical Problem

Existing welding equipment is unable to cope with changes in weld position caused by workpiece assembly errors and thermal deformation in nuclear power structural components. It cannot simultaneously weld symmetrical fillet welds and relies on complex track installation, resulting in poor adaptability, leading to low welding efficiency and unstable quality.

⚗Method used

An adaptive dual-gun cooperative magnetic rail welding device is adopted, which uses permanent magnet array adsorption and lateral guide wheels to achieve trackless precision movement. The welding gun position is finely adjusted by a two-dimensional cross slide with X-axis and Z-axis linear slides. The weld position deviation is compensated in real time by a floating buffer mechanism, and the integrated control system realizes automated control.

🎯Benefits of technology

It improves the stability and precision of the welding process, enhances welding efficiency and quality, reduces operational difficulty and installation costs, and strengthens the versatility of the device.
