Ultracold-Wire and arc additive manufacturing (UC-WAAM)
Journal of Materials Processing Technology, 2021Abstract This study presents a new variant of Wire and Arc Additive Manufacturing named Ultracold-Wire and Arc Additive Manufacturing (UC-WAAM), in which the electric arc is established between the wire feedstock material and a non-consumable tungsten electrode. A feasibility study was performed on HSLA steel. A comparison with conventional Gas Metal

This chapter summarizes a PhD thesis introducing a methodology for optimizing robotic MIG (metal inert gas) to perform WAAM (wire and arc additive manufacturing) without using machines equipped with CMT (cold metal transfer) technology. It tries to find the optimal MIG parameters to make WAAM using a welding robot feasible production technique capable ...

Material efficient WAAM Steel Construction Details
IABSE Congress Reports, 2023<p>With the new manufacturing process Wire Arc Additive Manufacturing {WAAM), it is possible to produce new shapes that previously could only be manufactured with a great effort. The energy- intensive manufacturing process can be positively compensated by the sensible use in mainly material-saving components.

WAAM: Wearable Assessment Arm Motion System
2019 12th Biomedical Engineering International Conference (BMEiCON), 2019The stroke patient needs to get an assessment for planning the recovery process, which is used to prepare an appropriate rehabilitation. Fugl-Meyer assessment is a popular protocol that covers all levels of physical conditions, but generally the protocol must be used by an expert for an accurate result.

Investigation of Corrosion in WAAM Manufactured Materials
CONFERENCE 2022, 2022Abstract To develop the commercial applicability of Wire-Arc Additive Manufacturing (WAAM), there is a crucial need to understand the corrosion behaviour of the fabricated materials for industry acceptance. It is well-known that WAAM process has a complex thermal process, resulting in unique microstructures and material surfaces.

Additive manufacturing using WAAM with AA5183 wire
Journal of Materials Processing Technology, 2018Abstract The present study addresses wire arc additive manufacturing of AA5183 aluminium alloy using conventional gas metal arc welding deposition on 20 mm thick AA6082-T6 plate as support material. Microscopic examination demonstrates that the process is feasible, but can be further optimized to reduce gas porosity and hot cracking.

Konstruktive Randbedingungen bei Anwendung des WAAM-Verfahrens
2020Das Wire and Arc Manufacturing (WAAM) verspricht eine hohe Produktivitat bei im Vergleich zu anderen Verfahren geringeren Kosten aber gleichzeitig geringerer Genauigkeit der hergestellten Bauteile. Aufgrund des spezifischen Verfahrensablaufs ist die erfolgreiche Herstellung von Funktionsbauteilen geknupft an Prozess und Geometrie.
