Siemens Energy and GEFERTEC Bring WAAM to Serial Production, Steam Turbine Blades Reach Thousand-Unit Manufacturing
2026-05-05
Siemens Energy and GEFERTEC will showcase the serial production results of Wire Arc Additive Manufacturing (WAAM) for steam turbine blades at the WAAMathon 2026 in Berlin on June 11. Traditional casting processes are limited by material procurement lead times and a 70% machining scrap rate, while WAAM's near-net shaping improves material utilization from approximately 30% to 80%, reduces delivery time by 75%, and achieves cost savings of about 15%. In fall 2023, Siemens Energy produced its 1,000th turbine blade using WAAM, becoming the first company globally to achieve serial production in this field. Challenges for WAAM include converting highly twisted turbine blade geometries into a stable, repeatable additive process and the lack of available certification standards.

西门子能源与GEFERTEC将WAAM带入批量生产，蒸汽涡轮叶片迈入千件级制造
西门子能源与GEFERTEC将在6月11日柏林举办的WAAMathon 2026上，展示电弧增材制造（WAAM）在蒸汽涡轮叶片领域的批量生产成果。传统铸造工艺受限于材料采购周期和70%的机加工废料率，而WAAM通过近净成形将材料利用率从约30%提升至80%，交货时间缩短了75%，成本节约约15%。西门子能源已于2023年秋季用WAAM工艺生产了第1000个涡轮叶片，成为全球首家在WAAM领域实现批量生产的企业。WAAM工艺面临的挑战包括高度扭曲的涡轮叶片几何形状向稳定、可重复的增材工艺转换，以及缺乏可用的认证标准。
