cupronickel welding

The Cupronickel, also called Cu/Ni, are the most used alloys in the marine environment thanks to their high resistance to saline corrosion and biofouling.
The Cu/Ni 90/10, the alloy made by 90% Copper and 10% Nickel, is the most used because it can be applied to the vast majority of cases and because of its low costs.
The Copper-Nickel alloys are vastly used on offshore platforms in the Oil & Gas sector and in the naval sector, both commercial and military.

Why choose New Welding for the welding of structures in Cupronickel Cu/Ni 90/10

Welding perfectly and flawlessly the Cupronickel is not easy, it requires an accurate preparation of the parts to be welded. The welding can be executed in correct conditions only if the parts to join are perfectly clean and without grease or oxidations.
Our company, besides taking all the necessary precautions, owns both the European certification for welding EN, and the American one ASME.
We work with the most important companies that operate and produce structures on oil platforms of the most prestigious brands worldwide.

The welding of Copper – Nickel alloys

The Copper – Nickel alloys can be easily welded with all the conventional processes, since they have a simple metallurgical structure.
However, it is necessary to adopt some simple but precise measures, essential to the quality and durability of the weld. An example are the micro pollutions transmitted by the disks of the grinders used to clean the weld, that with time might show signs of breaking or cracks.
Even the borders of the metals have to be accurately prepared and worked on in a way to obtain the right “V” inclination.
It’s useless to point out that the skill and familiarity of the welder play a fundamental role throughout the whole process.
Lastly, but not less important, is the attention we dedicate to the welding of pipes, in which we use the same gas for the welding of the protection and the following internal finishing.
