| Abstract Scope |
Compared to powder based additive manufacturing technologies, WAAM provides the advantage of generating large size components at a lower cost. However, to this day, it does not lead to parts as thin, accurate and flawless than powder techniques. The WAAM technological issues are closely linked to the operating parameters and to the thermal cycles endured by the piece during its production.<br>This work, dealing with Gas Metal Arc Welding (GMAW) process applied to the SS304L, aims:<UL><LI>to develop an equivalent source thermal model in order to predict temperature gradients underwent by metallic pieces;</LI><LI>to assess the impact of operating parameters (heat input, substrate thickness or deposition strategy) on the part distortion. </LI></UL><p> The final purpose is to conduct to the development of a numerical model coupling thermal, mechanical and metallurgical aspects of the WAAM process which should give the possibility to foresee distortions and thus to design sustainable pieces.</p> |
