“…Several literature works presented deposition strategies for Direct crossings. For example, Ugla et al [27] and Mehnen et al [28] presented deposition strategies developed and tested specifically for the WAAM process, hence suitable for the implementation in the proposed CAM software. The most relevant deposition strategies for Direct Crossings developed in the aforementioned papers are presented in Fig.…”

WAAM (Wire-Arc-Additive-Manufacturing) is a metal additive manufacturing process using arc welding to create large components with high deposition rate. The workpiece quality and the process productivity are strongly dependent both on the process parameters (wire feed speed, voltage and current) and on the selected deposition path. Currently, the CAM (Computer-Aided-Manufacturing) software dedicated to WAAM rely on a multi-pass strategy to create the component layers, i.e. each layer is built overlapping multiple welding passes. However, since WAAM can create wide layers, a single pass strategy can improve the process efficiency when dealing with thin walled components. This paper proposes CAM software dedicated to WAAM, using a single pass strategy. The proposed solution uses a midsurface representation of the workpiece as input, to generate the deposition toolpath. A feature recognition module is proposed, to identify the critical features of the part, such as free end walls, t-crossings, direct-crossings and isolated tubulars. A specific strategy is developed and proposed for each one of the selected features, with the aim of minimizing the geometrical errors and to ensure the required machining allowances for the subsequent finishing operations. The effectiveness of the proposed strategy is verified manufacturing a test case.

“…Indeed, in GMAW process, a part of the arc power is delivered directly to the substrate while the remaining part is consumed in melting the filler metal and then t Err transmitted to the workpiece by means of the molten filler droplets enthalpy [26]. As a first approximation, 50% of the total power is assumed to be delivered to the substrate and the remaining 50% to the filler metal [27]. Since the Goldak heat source prescribes a Gaussian distribution, achieving such power subdivision requires a tuning operation of the ellipsoid semi-axes dimensions, usually selected according to the molten pool dimen-sions.…”

“…The SMD method with MIG welding has been a well-established technique for producing metal objects, often by melted welding wires in subsequent layers [11]. SMD can be utilized for any material that can be deposited and is now being researched for many metals, including Ni alloys [15], steels [16][17][18], and Ti alloys [19][20][21][22]. The microstructure properties revealed that the TW-SMD layers' structure reflected the SMD layers with big, elongated grains that became epitaxially and inclined in the opposite direction to the layers when temperatures gradient caused by the part's movement of the welding head, whereas the UTS varies within 929 and 1014 MPa depending on specimen orientation and their location.…”

Additive manufacturing (AM) is a highly advanced manufacturing technology that involves metal layers deposition in order to increase the efficiency of component production and costs reduction. Current study includes examining the effects of adding aluminium as an additional alloying element to austenitic stainless-steel SS 309L. Metal Inert Gas (MIG) welding apparatus was used as a heat source for the deposition of the steel in the Wire Arc Additive manufacturing method. Simultaneously during the building process, three different percentages (0, 2.5%, and 5%) of an external aluminium alloy 4043 (E4043) cold wire was introduced into the fusion zone. The focus of the study is to highlight the influence of adding E4043 on the microstructure and mechanical properties of additively manufactured SS309L. For the microstructural investigations, optical microscopy and scanning electron microscopy (SEM) were used, whereas a Vickers microhardness test was used to investigate the effect of these additions on the local mechanical properties. On the other hand, the mechanical behavior of the deposited parts was examined using tensile test. The results of the study demonstrated that the addition of the aluminum alloy is significantly affect the mechanical properties of the deposited portions. The quantity of the added aluminum is discovered to have an influence on the microstructure, hardness, and tensile strength. Moreover, the homogenizing thermal treatment improved the samples' microstructure and overall properties. The found results highlights the importance of considering double wire feeding in additive manufacturing processes to reach the desired microstructural and mechanical properties in the final products.
