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.

Depending on the size of the trailing gas nozzle, the gas consumption is approximately between 20 and 40 litres/min. With this amount of gas, a much larger area can be covered on the component than is possible, for example, with welding torches with large gas lenses.

OSCAR-PLT can select the right nozzles for you. The size and geometry of the nozzles can vary greatly depending on the process. Our service includes process analysis, welding tests, nozzle design, structural integration and on-site commissioning. The selection of the right nozzles depends on several factors, including the material to be welded, the welding process used and the system environment.
