AI Technical Summary

Technical Problem

The presence of deposits on the outer periphery of the subsea oil pipeline prevents the laser welding head from accurately targeting the crack, resulting in poor repair results. Furthermore, unevenness in the contact between the equipment and the pipeline causes repair deviations.

Method used

A laser additive manufacturing device for marine engineering equipment has been designed, including a sealed shell, a laser welding component, a drive component, a moving component, a removal component, a positioning component, and a spring switch. By flexibly adjusting the spacing and positioning of the components, the attached material is removed step by step, ensuring that the laser welding head accurately acts on the crack and improving the welding stability.

Benefits of technology

Effectively removes deposits from the outer periphery of oil pipelines, ensures precise laser welding of cracked areas, improves repair accuracy and stability, and guarantees pipeline repair results.
