Additive Manufacturing solutions

Vallourec has introduced new solutions to enhance the future of the metallic component value chain for various markets through Wire Arc Additive Manufacturing (WAAM).

This technology utilizes the process of additive manufacturing, which involves constructing a 3D object by adding material in successive layers. As part of the Direct Energy Deposition (DED) process family, WAAM can create shapes that are not achievable through traditional casting or forging and provides short lead times. With its versatility, the technology can cater to a wide range of applications and needs. The company’s material expertise, quality standards, and industrial framework form the foundation of this innovative offering, enabling the delivery of finished and certified parts.

On-demand production
Optimized design for large metallic parts
Short lead times
Faster delivery in remote locations
Cloud-based inventory
Digital warehousing
Wire Arc Additive Manufacturing

For large metallic components, WAAM is the most promising and fastest 3D printing technology. With it we can design, print and fully qualify metal parts to the highest standards of quality. It offers you greater efficiency and shorter lead times, allowing you to revolutionize how you manage your assets.

How does the 3D printing work?

WAAM uses an electric arc controlled by a robotic arm to melt metal wire directly onto the surface of the base, layer by layer.

How does it impact supply chain?

WAAM does more than create a physical product, it offers the ability to create a digital warehouse so you can cut down physical storage costs and improve your supply chain efficiency by obtaining parts on demand.

How flexible is the process?

WAAM offers the opportunity to shape the part you need in a variety of materials. It provides total freedom to create new designs and new functionalities.

A one-of-a-kind-line

Designed with state-of-the-art technologies (component printing and ultrasonic inspection) capable of manufacture with short lead times (<4weeks).


With existing traditional operations to address market requirements.

Printing area of 2m3

L=1m x l=1m x H=2m

A new technology gaining ground

  • Carbon steel components are qualified with a pressure test up to 22,500 psi
  • Quality plans are available with reference to standards and norms
  • New corrosion resistant alloys under qualification in R&D to be available soon
Digital Warehousing


We support your move toward digital warehousing
WAAM radically changes the concept of warehouse logistics. Major O&G companies are increasingly turning to additive manufacturing to improve the agility of their supply chain, to reduce their physical stock and to establish a distributed network of manufactured parts by storing additive manufacturing digital files to be printed upon demand.

Customer Story
Safety-critical Sealing Ring for EDF Hydro’s Hydroelectric Facilities


Vallourec has manufactured the first safety-critical sealing ring using Wire Arc Additive Manufacturing for EDF Hydro’s hydroelectric facilities. This component, manufactured in martensitic stainless steel, is 1-meter long in diameter and weighs approximately 100kg. “Today, we have proved the benefits and the process of this technique and now we would like to scale up production and benefit from this new supply method in our facilities, which will involve thousands of components.” Sylvain Guyot, Additive Manufacturing Lead at EDF Hydro.

3D-Printed Lifting Plug Deployed in Timor Sea


Vallourec has recently produced 2 lifting plugs using Wire Arc Additive Manufacturing (WAAM) meeting Weatherford’s urgent operational demands. The 3D-printed safety-critical components weighed 175kg each with a tailor-made diameter of 50cm and were designed for load carrying applications of around 100 metric tons. “We were extremely happy with the finished product and will look to Vallourec and this method for future requirements.” Shane Ferguson - Project Manager for Weatherford

3D-Printed Waterbushing with TotalEnergies


Vallourec has equipped TotalEnergies with a 3D printed waterbushing for the EIG well in the North Sea. “This is the first time that a safety-critical component has been created using additive manufacturing in the Energy industry. It was essential for us to have the right partner and a good business case. Vallourec, as a longstanding partner, provided us with that confidence.” Edwige Ravry, Additive Manufacturing Lead at TotalEnergies

X-over production with DNV GL


The objective of the project was to perform a full-size physical component test in order to assess the performance of a WAAM manufactured product. The test has been successfully conducted with Internal Pressure (15,000 psi) combined with Tension, Compression loads (400 kips) and elevated temperature up to 130°C. Ultimately, concluding with a burst test with a pressure up to 30,000 psi without failure (50% above plastic deformation).
