For Laser System Integration: A Gas Jet Nozzle Option for
Gas assisted laser cutting
A high pressure gas jet nozzle enhances laser cutting and provides the following features as an industrial laser processing accessory:
What it does:
• Utilizes gas pressure to assist laser cutting, usually air
• Provides cooling of laser generated heat
• Slag removal
• Inert gas shield (N2)
• Reactive gas (O2) cut
Gas assisted laser processing requires clean, dry gas. If air is used, devices are needed to filter and dry the air plus pre- and post-regulators to set air pressure and a valve to control on/off. These devices are typically wall mounted and connected to an air compressor.
Cooling and slag removal
Inert gas, cooling & slag removal
Cut steel typically
When using air for the nozzle, higher pressures up to 60 psi are useful for cooling. Air serves both a cooling and slag removal function.
Nitrogen, as an inert gas shield, removes oxygen from around the work site. Whereas, oxygen, as a nozzle gas, creates an exothermic reaction to “set the material on fire”.
• Usual Pressure: 60 psi
• Mounting: Standard M26 thread
• Option: Gas supply system (filters, desiccators, regulators & valve)
