Fronius will launch a dedicated welding source for Wire-Arc AM systems in 2024. Together with several partners, Fronius has already demonstrated that it can print certified parts that are leak-tight at high pressures.
Last week, the Austrian manufacturer of welding technology showed the first WAAM products at the Schweissen und Schneiden welding fair in Essen. In November it will participate in Formnext. there it already provides more information regarding the new products.
Better control of heat input for more robust welding process
Cost-efficient production method
“WAAM is a cost-efficient production method for prototyping, small series and complex products,” said Philipp Roithinger of Fronius at the trade fair in a tech talk regarding the new development. MX3D, among others, currently uses a CMT welding source from Fronius in the WAAM systems. These weld at a lower temperature. The new welding sources have been improved on a number of points. This mainly concerns control over the welding process and heat input. Fronius also works with wire manufacturers on better solutions for WAAM.
Future: Download standardized parameter settings
Philipp Roithinger: “What we are concerned with is improving the robustness of the process. We expect you to download a recipe for a certain material and geometry in the future. We are not there yet, we still have to develop parameters for that.” Fronius wants to develop and standardize WAAM to such an extent that the process becomes much simpler and the outcome more predictable. The impeller that was shown in two sizes at Schweissen und Schneiden is an example of this. The larger version is printed with the same parameters as the smaller one.
Certified part
Also has Fronius together with Linde, TüV Süd and Migal, among others, printed a pressure vessel according to standard qualifications. The volume is 31 liters and must withstand a pressure of 45 bar between -196 degrees C and + 60 degrees. The wall thickness increases from 7 mm to 17 mm and the whole is printed on an existing part. The printing time was 3 hours and 40 minutes. The part has been tested for leak tightness at a pressure of 64.4 bar and has passed this test well.
