Depending on the component properties, we can apply targeted coating in the interior area up to a distance of 100 mm based on different available focus lengths.

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.

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.
