摘要
电弧增材制造(WAAM)是一种用于在钢中建立三维结构的焊接工艺。与其他增材制造技术一样,它允许制造几何形状特殊的结构,否则使用传统方法制造是不可行的或非常昂贵的。本文提出了一种在大规模应用环境中使用WAAM的集成设计方法,重点关注具有特殊几何复杂性的列。它结合了材料性能和工艺参数研究,目的是提供使用WAAM设计和打印结构的数字工具。为了实现所需的几何形状,必要的焊接参数被存储并应用到基本的数字孪生模型中。这是由多个过程控制检查补充的,这些检查在打印过程中实现,以确保按计划生成对象。最后,这些结构被制造出来,并受到严格的评估,以确定未来可能的潜力。将几何复杂性与大规模制造相结合的挑战代表了WAAM在钢结构中集成的下一步。兰格,j .;Waldschmitt b;Costanzi, C.

Wire Arc Additive Manufacturing (WAAM) is a welding process used to build up three-dimensional structures in steel. Like other Additive Manufacturing technologies, it allows for geometricallyexceptional structures to be fabricated which are otherwise unfeasible or very expensive to manufacture using traditional methods. This paper presents an integrated design approach to the use of WAAM in the context of large scaled applications, focusing on columns with exceptional geometric complexity. It combines material behaviour and process parameter research, with the aim of providing a digital tool to design and print structures using WAAM. To achieve the desired geometries, necessary welding parameters are stored and applied to a rudimentary digital twin model. This is complimented by multiple process-control checks, which are implemented during the printing process to ensure that an object is generated as planned. Finally, the structures are manufactured and are subjected to a critical evaluation in order to identify the possible future potential. The challenge of combining geometric complexity with manufacturing for large scale represents a next step in the integration of WAAM in steel constructions. Lange, J.; Waldschmitt, B.; Costanzi, C.
