AI Technical Summary

Technical Problem

During laser welding, molten metal particles can easily splash onto vulnerable parts such as nozzles, resulting in a short service life. Existing technologies use physical baffles to intercept these particles, but this requires frequent shutdowns for cleaning, which affects production efficiency.

Method used

An auxiliary gas path is set in the laser welding equipment so that the auxiliary gas is sprayed along the tangential direction of the main gas path to form a vortex airflow, which throws out molten metal particles and forms a dynamic pressure barrier through the inner and outer gas layers to intercept spatter particles and reduce damage to the nozzle.

Benefits of technology

It effectively prevents molten metal particles from splashing onto the nozzle, extending its service life, reducing downtime for cleaning, and improving production efficiency.
