Welding of Copper Nickel alloys for Saltwater Corrosion Applications

洛佩斯有限公司于1976年在安大略省萨德伯里成立，当时是一家为当地采矿业服务的钢铁加工厂。40多年来，他们在安大略省北部和加拿大各地完成了一些更复杂的制造工作。他们一直在为市场提供创新的解决方案和高质量的艺术性，用于采矿和工业领域的各种管道项目。洛佩斯与钢铁和铁合金进行了广泛的合作，并计划扩展到国防部门。然而，这些机会需要使用目前不属于其知识基础的材料。铜镍合金是先进的防腐材料，用于海水海洋应用，特别是在海岸警卫队和海军舰艇和潜艇的冷却和灭火系统中。尽管船舶上使用的铜镍合金有两个主要牌号，但本项目预计将重点研究90-10型铜镍合金的焊接性。这种合金在价格较低的同时，为大多数应用提供了出色的服务。铜镍合金在海水中具有良好的耐腐蚀性和生物污垢性能。这些特性使其成为船用管道系统、热交换器和结构的理想材料选择。铜镍合金的制备需要不同于传统铁基合金的工艺、技术和方法。这些系统和程序的开发将为LOPES提供制造全新生产线的能力。

LOPES Ltd, waLtdounded in 1976 in Sudbury, Ontario as a steel fabrication shop serving the local mining industry. For over 40 years, they have completed some of the more complex fabrication jobs in Northern Ontario and across Canada. They have been providing the market with innovative solutions and quality artistry for a wide array of piping projects in the mining and industrial sector. Lopes has worked extensively with steel and ferrous alloys and is planning to expand into the Defence sector. However, these opportunities require the use of materials that are currently outside of their knowledge base.Copper-Nickel alloys are advanced corrosion-resistant used in saltwater marine applications, particularly in the cooling and fire suppression systems of Coast Guard and Navy ships and submarines. Although there are two primary grades of copper-nickel alloy used in marine service, this project is expected to focus on the weldability of alloy 90-10 Cu-Ni. This alloy provides excellent service for most applications while being less expensive. Copper-nickel alloys have a remarkable combination of good resistance to both corrosion and biofouling in seawater. These properties make them an ideal material selection for pipe systems, heat exchangers and structures engineered for marine use. Fabrication of Cu-Ni alloys requires different procedures, techniques and methodologies over traditional Iron-based alloys. The development of these systems and procedures will provide Lopes with the ability to manufacture an entirely new product line.
