Wire Arc Additive Manufacturing (WAAM) is a manufacturing process used to produce or repair metal parts by 3D printing. It belongs to the direct energy deposition (DED) family of additive manufacturing processes. WAAM is realised by layering layers of metal on top of each other until a desired 3D shape is created. It is a combination of two manufacturing processes: gas metal arc welding (GMAW/MIG) and additive manufacturing. GMAW (MIG) is a welding process used to join metal parts using an electric arc, and additive manufacturing is an industrial term for 3D printing. Part production using WAAM is performed by a welding robot integrated with a power source. A welding torch connected to the robot is used to melt wire feedstock to create 3D parts.
Here are some of the industry-based applications and highlighted advantages;
Defence : WAAM can be employed to fabricate custom mounting brackets for military vehicles, UAVs, or weapon systems. By leveraging WAAM technology for the production of such components, defense organizations can achieve a balance between functionality, weight reduction, and customization, thereby improving overall mission effectiveness and operational efficiency.
Aviation and Aerospace : WAAM can revolutionize aviation and aerospace by enabling the crafting of lightweight, custom components, enhancing fuel efficiency and operational effectiveness while optimizing the buy-to-fly ratio.
Maritime : WAAM presents transformative opportunities for the maritime sector by facilitating the production of Propeller, Crane Hook and Panama Chock and so on. These innovations enhance vessel and ships performance and efficiency while streamlining production processes.
Oil and Gas : WAAM in the Oil & Gas industry introduces transformative solutions, including the fabrication of corrosion-resistant piping components, innovative heat exchanger designs, and custom flanges for connectors. This technology enhances operational efficiency, addresses specific challenges such as deep-sea wellhead reinforcement, and enables on-site fabrication in remote locations, showcasing its potential for customized, high-performance components in critical applications.
Railway : WAAM technology in the railway industry can reshape production of components, enabling customized, high-performance solutions. WAAM’s capabilities extend to efficient repairing of worn-out railway components and providing robust cladding solutions for enhancing the durability and longevity of critical railway infrastructure.
During the WAAM process, a dense fume is generated in the cell. It is imperative that this fume is evacuated as quickly as possible. This smoke is very dangerous for human health and the environment.
With our systems specially produced by HIVENT, it is removed and filtered from the cell in the fastest way possible.
