Abstract Wire-arc additive manufacturing (WAAM) provides an alternative for the production of various metal products needed in medium to large batch sizes due its high deposition rates. However, cyclic heat input WAAM may cause local overheating. To avoid adverse effects on performance part, interlayer dwelling and active cooling are used, but these measures increase process time. Alternatively, temperature during could be controlled by optimizing welding power. The present work aims at...

Conventional metal manufacturing techniques are suitable for mass production. However, cheaper and faster alternatives preferred small batch sizes individualized components. Directed energy deposition (DED) processes allow depositing metallic material in almost arbitrary shapes. They characterized by cyclic heat input, hence heating cooling every point the workpiece several times. This temperature history leads to distribution of mechanical properties, distortions, residual stresses or even...

Additive Manufacturing (AM) provides the possibility to produce complex part geometries on a layer-by-layer basis. In AM processes, heat source moves over either deposit powder or wire feedstock melt thin layers that are spread onto bed. The moving inevitably creates an inhomogeneous temperature distribution, which affects residual stresses, distortion, and local mechanical properties. Accumulation of in corners path intersections may result overheating hence defects. this study, method for...

Production of components through forming requires extensive machining, high tool costs and long manufacturing times. Wire Arc Additive Manufacturing (WAAM), a direct energy deposition process, uses conventional arc welding technology to generate complex near net shape 3D parts. In Wire-Arc moving heat source melts the electrode wire deposits metal on substrate. The movement creates different heating cooling patterns at locations causes distortions in substrate part. This work presents method...

In modern manufacturing processes such as hot forming or additive manufacturing, the workpiece material undergoes very complex thermomechanical load cycles.

Cladding is typically used to protect components from wear and corrosion while also improving the aesthetic value reliability of substrate. The cladding process induces significant residual stresses due temperature difference between substrate clad layer. However, these could be effectively utilized by modifying processes geometrical parameters.
