Laser Nozzle-Shield

Easy-to-use gas nozzle optimizing gas flow distribution.

Laser Nozzle-Shield is an easy-to-use gas nozzle designed by Air Liquide to optimize gas flow distribution. It results in a significant decrease of air contaminants such as O2 and H2O in the weld pool. It is compatible with all laser welding processes and gases, including argon, helium or mixtures.

The shielding gas distribution nozzle is a key operational component, which has a direct effect on the efficiency of the CO2 and solid-state laser welding process. Poor equipment design or adjustment can cause air inlets in and around the interaction zone, resulting in welding defects or weld bead oxidation.
