Wire Arc Additive Manufacturing Waam Process

Wire arc additive manufacturing waam uses an electric arc as a heat source and wire rather than powder as feedstock.

Wire arc additive manufacturing waam process. The wire arc additive manufacturing waam process used to manufacture aluminum parts has a number of variables. Welding power source torches and. Wire arc additive manufacturing process waam wire and arc additive manufacturing is a technique that fabricates extruded 3 d shape components by layer by layer deposition of metal wire in which the wire is fed to the electric arc at a controlled condition and environment based on the needs of the material 13. Arc welding based additive manufacturing or waam techniques are attracting interest from the manufacturing industry because of their potential to fabricate large metal components with low cost and short production lead time.

Diseño análisis y desarrollo de una célula fabricación basada en tecnología aditiva waam par piezas de alto valor añadido. This study focuses on the effects of the heat input and the current and voltage ratio on the deposition efficiency. Academia working closely with industry to mature the wire arc additive manufacturing process targeting process qualification and full industrial adoption of a processing technique which is revolutionising the world of manufacturing. Wire arc additive manufacturing waam the combination of an electric arc as heat source and wire as feedstock is referred to as waam and has been investigated for am purposes since the 1990s although the first patent was filed in 1925.

Waam can be achieved with various energy sources including gas metal arc welding gmaw 2 gas tungsten arc welding gtaw 1 and plasma arc welding paw 4. Unlike the more common metal powder am processes waam works by melting metal wire using an electric arc as the heat source. Waam is a variation of a direct energy deposition technology and uses an arc welding process to 3d print metal parts. This process exists alongside other high deposition rate metal am technologies such as powder and wire based ded.

How does wire arc additive manufacturing work. One of the advantages of waam technology is that it can be implemented using off the shelf welding equipment which makes it an appealing option for job shops that don t want to invest in an expensive powder bed system.
