Abstract

Wire-arc directed energy deposition (DED-Arc), also known as wire arc additive manufacturing (WAAM), brings about unprecedented opportunities in the construction sector to improve material efficiency, enhance automation and reduce embodied carbon. To address the current standardisation gap, a normative framework for the use of DED-Arc in construction is proposed in this paper. The current standardisation landscape for additive manufacturing and steel construction is firstly introduced. The standardisation requirements for DED-Arc in construction, encompassing qualification, structural design and execution, are outlined. A quality classification system for DED-Arc construction products and qualification requirements for the manufacturing process and finished parts are required. Regarding the structural design, modifications and additional rules to the Eurocode 3 are needed for DED-Arc structural components, in terms of design material and geometric properties, design methods, reliability and design for long-term and extreme actions. Finally, additional requirements for the execution of steel structures featuring DED-Arc are discussed.

建筑业金属增材制造标准化框架

线弧定向能沉积（ed -arc），也被称为线弧增材制造（WAAM），为建筑行业带来了前所未有的机会，可以提高材料效率，增强自动化和减少隐含碳。为了解决目前的标准化差距，本文提出了在建筑中使用d - arc的规范框架。首先介绍了增材制造和钢结构的标准化现状。概述了在施工中对电弧弧焊的标准化要求，包括资质、结构设计和施工。对电弧弧焊结构产品的质量分级体系和制造工艺及成品的合格要求是有必要的。在结构设计方面，在设计材料和几何性能、设计方法、可靠性以及长期和极端作用的设计方面，需要对欧洲规范3进行修改和补充规则。最后，讨论了d -弧钢结构施工的附加要求。

期刊介绍： Automation in Construction is an international journal that focuses on publishing original research papers related to the use of Information Technologies in various aspects of the construction industry. The journal covers topics such as design, engineering, construction technologies, and the maintenance and management of constructed facilities. The scope of Automation in Construction is extensive and covers all stages of the construction life cycle. This includes initial planning and design, construction of the facility, operation and maintenance, as well as the eventual dismantling and recycling of buildings and engineering structures.
