ABSTRACT

Increasing competition in the international shipbuilding industry pushes the naval architect’s pressure to reduce the costs of design and manufacturing of new buildings. Using newly developed Additive Manufacturing (AM) methods in the framework of industry 4.0 revolution can offer new opportunities in the manufacturing of labour-intensive and complex parts. Wire Arc Additive Manufacturing (WAAM) is a promising candidate for the manufacturing of large-scale metal parts, especially complicated double-curved parts (e.g. bulbous bow, propeller, rudder, etc.), in a more design flexible and cost-effective way in the shipbuilding industry. This article reviews the new developments of WAAM technology and discusses the feasibility of application of WAAM in the shipbuilding industry in the framework of material availability and properties, design complexity and cost by giving current and possible future applications.

摘要

国际造船业日益激烈的竞争推动了造船工程师降低新建筑设计和制造成本的压力。在工业 4.0 革命框架中使用新开发的增材制造 (AM) 方法可以为劳动密集型和复杂零件的制造提供新的机会。电弧增材制造 (WAAM) 是制造大型金属零件，尤其是复杂的双曲面零件（例如球状船首、螺旋桨、方向舵等）的一种很有前途的候选方法，其设计更加灵活且更具成本效益在造船业。本文回顾了WAAM技术的新发展，并在材料可用性和性能的框架内讨论了WAAM在造船行业应用的可行性，
