| Abstract Scope |
With the wire-arc additive manufacturing (WAAM) complex components can be built up layer by layer from metallic construction materials. In this investigation two different WAAM processes with high built-up rates (CMT and pulsed GMAW) were compared in terms of geometry formation and component properties. The reference is a rectangular thin-walled geometry made of the austenitic stainless steel 316LSi (1.4430). During the welding process, the temperature development in the base plate as well as in the weld layer were measured. The experimental comparison of CMT (Rm=630MPa) and pulsed GMAW (Rm=605MPa) is completed by the determination of the mechanical properties using micro tensile tests. Furthermore, the additive manufactured walls were cold rolled with a subsequent heat treatment or hot rolled to provide proof of formability and forming induced property improvement. |
