Gas nozzle cross
jet
During welding, depending on the energy density and material, the laser triggers a plasma
flare of a varying height which absorbs the laser light.
At constant laser output a penetration of different depths is created.
To ensure constant penetration despite the plasma flare, it is possible to use the gas nozzle
cross jet.
The gas nozzle cross jet uses compressed air to generate a fine current of air that cuts off
the plasma flare at a defined height.
IMPORTANT!
-
Because the gas nozzle cross jet is situated very closely to the opening of the gas out-
let this can result in swirling gas and subsequently: pores.
-
Furthermore, if the air current experiences resistance this can lead to acute pore for-
mation.
-
The plasma flare contains welding spatter and welding fume. If the plasma flare is
blown out, the surrounding area will be severely polluted.
Scope of Application:
-
For freely accessible components
-
For a laser output of at least 4 kW
-
Mainly for butt welds with a full penetration root pass or where precise welding pene-
tration depth is required
