Our drag gas nozzles are not wear parts, but are designed for continuous operation. There are replaceable wear parts in the nozzle body that can be replaced if they become heavily stained (e.g. by welding spatter).

We see our laser technology as an important and forward-looking addition to the mentioned processes. We can work dynamically on components and under normal conditions using localised shielding gas coverage. Minimising distortion and undesirable softening of the base materials are just some of the advantages that enable us to overcome production limits. With ProFocus, wire and powder materials can also be guided in one system and applied layer by layer, locally, and even in alternation, if needed. This flexibility does not exist with other processes.

Trailing gas nozzles offer improved shielding gas coverage. This leads to a reduction in oxidation (annealing colours), which is particularly important when welding stainless steel or titanium. Unwanted changes to the component, such as pores in the seam and burn-off of alloying elements, are minimised. The nozzles are designed to distribute the shielding gas more efficiently and evenly around the welding point, thereby keeping the oxygen away from the heat-affected zone on the component.
