Preliminary investigation of a fast temperature prediction approach for simple thin-walled parts produced with Wire Arc Additive Manufacturing

During Wire Arc Additive Manufacturing (WAAM), an arc welding process is used to deposit material. The evolution of temperature during the a key aspect affecting accuracy and mechanical properties. possibility predict therefore crucial for planning deposition sequence. Currently, Finite Element Method (FEM) well-established solution simulations. However, computational efficiency typically achievable with FEM limits its integration in phase. In addition FEM, Volume (FVM) also suitable numerical method simulating thermal problems, which could potentially deliver higher than FEM. A scheme able simulate WAAM proposed applicability tested test case derived from literature. By running implemented on CPU 64 cores, time more 100 times shorter real manufacturing was achieved, while keeping comparable results reported
