Twin-wire weld overlay cladding system developed
Subcontract weld cladding company's research and development team has developed a twin-wire system for weld overlay cladding - doubling deposition rate and reducing the HAZ.
The hull penetrator inserts, which as the name suggests are welded into the hull of the boat, are designed to allow external instrumentation connections to pass to the inside of the vessel.
As the inserts are part of the main structure, they have to be made from the same type of high strength steel as the hull itself.
Unfortunately the steel doesn't have the corrosion resistance needed to ensure a secure seal for the Seacon connectors, so the internal and sealing areas that are exposed to seawater were weld overlay clad with Monel 400, a 70% nickel 30% copper alloy that is acknowledged to be the ideal material for this environment.
Commenting for Orwelco, spokesman John Knight says: "Seacon had previous experience of Arc Energy's work and suggested we contact them.
After visiting their website, and subsequently their Gloucestershire factory, we were impressed with what we saw and heard.
The quotation that followed our technical meetings was also acceptable and they were awarded the contract." He further reports that Arc Energy's element of the project was completed on time, and Orwelco and Seacon were delighted with the company's performance.
So much so in fact, that Seacon has awarded Orwelco a contract for a further ninety hull penetrator inserts, which are also destined for Arc Energy to be clad.
