Coaxial processing head for laser wire buildup welding processes

Compared to laser powder buildup welding, laser wire buildup welding bears significant advantages such as 100% material utilization, clean processes, high surface quality and a low chemical reactivity due to smaller specific surfaces.

Thanks to the novel IWS COAXwire processing head, wires can now also be processed independent from direction with high geometric degrees of freedom. The smallest lateral resolution is currently 600 µm.

Practically, all commercial wire feeders can be processed. Typical examples are tool and stainless steels, INCONEL625, INCONEL718, TiAl6V4, AlMg5 as well as bronze and Zn-based model alloys.
