STELIA Aerospace, a French manufacturer of aerostructures and aircraft seats, has harnessed Wire Arc Additive Manufacturing (WAAM) technology to produce a demonstrator for metallic self-reinforced fuselage panels. The company designed and developed the 1
In aluminium welding, the alternating current TIG (ACTIG) process has been used because of its ability to allow setting of the proportions of electrode positive (% EP) to negative (% EN) time cycle to enhance oxide removal and fusion effect [8,12,13].
Wire Arc Additive Manufacturing (WAAM) uses arc welding to build up the component in layers. A metal wire is melted at the right place using a welding torch to form the desired blank. The rotating building platform means that the material build-up takes place across 5 axes with a …
La fabriion additive par soudage Certains procédés de fabriion additive métallique utilisent le soudage pour la réalisation de pièces avec le principe de fabriion couche par couche. C’est en particulier le cas du WAAM (Wire Arc Additive Manufacturing) qui est basé sur le soudage TIG + robot 6 axes ou le laser cladding (laser + poudre).
To date, most of the work in wire based DED has been carried out at Cranfield University, where a 6-m-long aluminium aero-structure was built in a few days. Research over the last 10 years has also proven the capability to make large titanium parts in a timely manner (weeks instead of months) and with much reduced cost (up to 70% cheaper than machining from solid), resulting in a tremendous
Yes, welding fumes contain oxides of the metals in the material being welded. Fluxes containing silica or fluoride produce amorphous silica, metallic silies and fluoride fumes. Fumes from mild steel welding contain mostly iron with small amounts of additive metals (chromium, nickel, manganese, molybdenum, vanadium, titanium, cobalt, copper etc.).

Wire and arc additive manufacturing based on cold metal transfer (WAAM-CMT) technology has the advantages of small heat input, small deformation, high welding speed and low operation cost. Because of these advantages, it is very suitable for the research of
This paper presents an experimental investigation of the fracture and fatigue crack growth properties of Ti‐6Al‐4V produced by the Wire + Arc Additive Manufacture (WAAM®) process. First, fracture toughness was measured for two different orientations with respect to the build direction; the effect of wire oxygen content and build strategy were also evaluated in the light of microstructure
Although Wire arc additive manufacturing (WAAM) has proven its capability of fulfilling demands of production of medium-to-large scale components for automotive and alli ed sectors made up of aluminium , at present WAAM cannot be applied as a fullyfledged
