Symposium 11th Conference on Trends in Welding Research + Additive Manufacturing (TWR+AM)
Presentation Title Key Learnings in Additive Welding of Super Duplex Stainless Steel in Pressure Vessel Application
Author(s) Manfred Schoerghuber, Wesley Doneth
On-Site Speaker (Planned) Manfred Schoerghuber
Abstract Scope The results of research and industry projects are presented. Special focus on Super Duplex Stainless Steel (SDSS) as a heat input sensitive material out of a research project form the Materials Technology Institute (MTI), as well as learning cycles to qualify an additive membrane valve. A bridged heat input qualification for welding SDSS does not guarantee high strength, high ductility and corrosion resistance. The MTI requirements were a comparison of the as-welded-state with results to solution-annealed-condition. Learning cycles with melting rate and oscillating strategy to reduce inner flaws were compared and made visible using computer tomography. New welding developments using polarity change, stabilators for arc length and deposition rate give secureness in heat input and repeatability. Included is tolerance displacement measurement by retracting welding wire signal, watching the welding process with a triggered camera, and an arc-sensor signal for process monitoring.
