WAAM

Metal 3D Printing and Advanced Die Regeneration

WAAM (Wire Arc Additive Manufacturing) is one of the most innovative technologies in the field of metal 3D printing. Based on the use of an electric arc and metal wire, it enables material deposition layer by layer, allowing the production of complex and large-scale components.

Compared to other traditional additive techniques, WAAM offers shorter production times and significantly lower costs, while maintaining high mechanical and metallurgical quality standards. This technology has established itself as a concrete solution for large-scale production, as well as for the maintenance and regeneration of industrial components.

DGWeld Robotic Cells Dedicated to WAAM

DGWeld has developed a range of robotic cells specifically dedicated to the WAAM process, integrating anthropomorphic robots and advanced control systems to ensure maximum process precision and repeatability.

Thanks to integration with the Fronius CMT (Cold Metal Transfer) system, DGWeld WAAM cells ensure:

• Uniform and controlled material deposition.
• Reduced porosity and residual stresses.
• Consistent metallurgical quality across the entire surface.
• Improved control of temperature and weld bead penetration.

These features make the WAAM process particularly effective for metal additive manufacturing, even in complex industrial environments or on large components.

WAAM for Intelligent Die Regeneration

One of the most interesting application areas of WAAM technology is the regeneration of worn or damaged dies.
DGWeld uses its WAAM robotic cells to provide advanced maintenance solutions capable of extending die service life and drastically reducing operating costs.

With Wire Arc Additive Manufacturing, it is possible to:

• Recover damaged dies without the need for complete replacement.
• Apply material only in critical areas, reducing machining time and material consumption.
• Use special alloys to improve resistance to wear and thermal fatigue.
• Achieve final performance equal to or superior to that of new components.

The result is an efficient and sustainable process that optimizes die maintenance and ensures production continuity at lower costs.

Industrial Applications of WAAM

Wire Arc Additive Manufacturing technology is used in numerous sectors of the metallurgical and forging industries. It is particularly suitable for companies requiring custom production, rapid prototyping, or the repair of large components.

Thanks to the combination of robotic automation and engineering expertise, DGWeld provides WAAM cells suitable for applications such as:

• Forging and hot stamping.
• Energy and oil & gas.
• Heavy mechanics and aerospace.
• Automotive and industrial equipment.
