Our trailing gas nozzles are very robust and durable. They are equipped with wear parts to withstand the thermal loads during welding as well as spatter, fumes and dirt. In addition, our nozzles can be designed with or without cooling, depending on the operating conditions. Furthermore, the gas distribution in the trailing gas nozzles and the outflow from the nozzle have been optimised using modern flow simulation methods so that the nozzles provide a laminar shielding gas film as quickly and efficiently as possible.

Yes, trailing gas nozzles can also be used for forming, e.g. in pipes or along joints. Sufficient space must be available so that the nozzle can be carried along. Particularly with large components, where a large volume needs to be formed, trailing gas nozzles offer the advantage of protecting the hot area locally around the seam more quickly and with less gas, instead of having to purge the entire area for a long time.

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.
