High-performance welding filler metals for the nuclear industry

Nuclear energy plays a crucial role in global electricity production, particularly in France where it accounts for 75% of the electricity generated. With over 60 reactors currently under construction in countries like China, South Korea, and the United Kingdom, the nuclear industry continues to grow and evolve. An essential component of this industry is welding, a process that must be carried out with the utmost precision and in accordance with the highest safety standards.

Selectarc has obtained the ISO 19443 certification, specific to the nuclear supply chain, which adds nuclear safety criteria to the ISO 9001 requirements. This certification guarantees quality, safety, competence, reliability, and traceability throughout our supply chain. Our clients and partners can thus be assured of maximum efficiency along with a constant focus on quality and nuclear safety.

Selectarc is a member of GIFEN to affirm its commitment to the French nuclear sector, contribute to its development, and benefit from a structured network serving the industry, both in France and internationally.
