The influence of process parameters on the residual asymptotic stress distribution is investigated using a 3D numerical modeling welding process. Computational mechanics and peak method are combined to calculate Notch Stress Intensity Factors (R-NSIF) as function power input. Results summarized in terms heat input discussed view future guidelines proposal addressed designers who going face opti...

Additive manufacturing based on robotic welding is used for the manufacture of metal parts by applying an arc as a heat source and wire feedstock. The process known additive (WAAM). However, current WAAM has limitation in fabricating block structure components with high geometry accuracy consistent due to complexity lack appropriate planning methods. Furthermore, common defects such voids, gaps...

Abstract: Microwave processing is one of the novel methods for combustion synthesis of intermetallic compounds andcomposites. This method brings about a lot of opportunities for processing of uniquely characterized materials. In thisstudy, the combustion synthesis of TiAl/Al2O3 composite via microwave heating has been investigated by thedevelopment of a heat transfer model including a microwave...
