Robotic additive manufacturing with WAAM technology

Wire Arc Additive Manufacturing (WAAM) represents one of the most significant advancements in the field of metal additive manufacturing. It is an advanced technology that uses an electric arc and metal wire to deposit material layer by layer, forming fully functional metal components.

Unlike traditional machining or casting techniques, the WAAM process enables the production of large-scale components with minimal material usage, drastically reducing production times, processing costs, and material waste.

When integrated into DGWeld robotic cells, WAAM technology delivers precision, repeatability, and consistent metallurgical quality, opening new opportunities in design, prototyping, and industrial component regeneration.

How WAAM Technology Works

The WAAM process uses an electric arc controlled by a robotic system to melt a filler metal wire, which is progressively deposited until the desired geometry is achieved.
Through digital management of welding parameters—such as voltage, current, travel speed, and temperature—DGWeld ensures full control of the deposition process and a uniform metallurgical structure.

By combining WAAM with complementary laser processes and intelligent monitoring systems, the company guarantees high-quality joints, excellent surface finishes, and extremely tight tolerances, even when working with materials that are difficult to weld or machine using conventional methods.

Advantages of WAAM in Industrial Production

The adoption of WAAM technology within DGWeld’s robotic cells offers several tangible advantages:

  • Reduced production lead times compared to traditional machining processes
  • Cost optimization, thanks to lower material consumption and the ability to regenerate existing components
  • Greater design freedom, enabling the creation of complex and customized geometries
  • Environmental sustainability, through reduced waste and lower energy consumption
  • Repeatability and consistent quality, ensured by digital control of all process parameters

These benefits make WAAM particularly suitable for industries that demand strength, precision, and reliability, such as aerospace, automotive, energy, heavy mechanics, and industrial forging.

Applications and Use Cases of WAAM Technology

DGWeld’s robotic additive manufacturing based on WAAM technology is used in three main application areas:

  1. Functional Prototypes
    WAAM enables the production of fully functional metal prototypes, allowing companies to test new geometries and innovative materials in a very short time. It is the ideal solution for validating a design before moving to serial production, reducing development risks and time-to-market.
  2. Custom Industrial Components
    DGWeld manufactures custom-made components according to precise technical specifications, minimizing material waste and improving production efficiency. WAAM cells are perfectly suited for the creation of structural parts, supports, brackets, and flanges with complex geometries and optimized mechanical properties.
  3. Repairs and Regeneration
    One of the most advantageous applications of WAAM is the regeneration of worn or damaged components, which are restored to their original operating conditions. This process is particularly effective for components that are difficult to replace or made from special materials, significantly reducing maintenance costs and downtime.

Materials Processable with WAAM

The flexibility of WAAM technology makes it possible to process a wide range of metals and alloys, including:

  • Steels and tool steels – ideal for manufacturing or restoring components requiring high strength and hardness.

  • Inconel and superalloys – perfectly suited for high-temperature applications and corrosive environments, offering excellent dimensional stability.

  • Stellite and carbides – materials characterized by high hardness and wear resistance, which can be deposited uniformly with minimal defect formation.

  • Aluminum – used to create lightweight yet robust components, with excellent mechanical properties and high-quality surface finishes.
