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).

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.

In addition to system development and production, we take on feasibility studies and application studies up to two to three items. To this end, we operate our own application center, where we also support our existing customers in process development and layer analysis. A number of contract service providers employ our technologies and we would be happy to put you in touch.
