Welding in the nuclear industry

Throughout our more than 150 year history, innovation and reliability have been the Sandvik hallmark. Already 60 years ago, alloys specifically tailored for the needs of the nuclear industry were developed. Today Sandvik has extensive experience in the industry by supplying welding products, steam generator tubing, nuclear fuel tubing and a variety of components for almost every part of a nuclear power plant.

We live in a big world with big needs. And a population that's growing exponentially. It's vital to find smarter, safer ways to use the energy resources we have. Nuclear power generates 15% of the global electrical power, and can together with renewable power sources reduce the world’s total CO2 emissions. We safeguard product and material properties throughout the manufacturing process by using optimum starting material, advanced production technologies and rigorous quality control. This is made possible by our in-depth materials manufacturing experience and fully integrated production, which means we control the entire process from melting of raw materials to the finished and tested products.

Our nuclear products are characterized by:

Chemical composition optimized for each welding process

Controlled ferrite content and extremely low impurity levels for resistance to hot cracking and microfissuring

Microelement control for optimum arc stability and wetting characteristics

Controlled wire surface for trouble-free mechanized welding

Alloy design for the best corrosion resistance and mechanical properties

Tough restrictions on B, Co, V and Cu content

Alloys optimized for post weld heat-treatment times up to 48h at 610°C, employed for longer service life

Sandvik is certified to a number of quality management system standards, such as the ASME NCA 3800, RCCM, ISO 9001, ISO 14001, OHSAS 18001 and ISO 50001, ensuring the highest quality standards, reliable deliveries, traceability as well as environmental and energy responsibility. The products we deliver to the nuclear industry include:

Strip electrodes for SAW and ESW surfacing on pressure containing base metals

Welding wire and rods for GTAW, SAW, GMAW in joining and surfacing operations

Covered electrodes in joining and surfacing operations
