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.

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.

Deposition welding with wire is the most material-efficient and safest laser technology. It is characterised by high availability, cost efficiency, easy handling and certified filler metal quality. It also minimises material loss and is harmless to health.
