"Multi-materials assemblies are designed and joined together to achieve the best performance for specific applications and specific working environments. These assemblies combine the advantages of each material into an advanced structure, capable of working in heterogeneous and harsh conditions. Dissimilar material assemblies are highly functional, save material resources and enable significant weight reduction, which is fundamental for breaking down fuel consumption and CO2 emissions (major targets for the transport industry).However, joining metallurgically incompatible metal alloys or CFRP composites to metal alloys is challenging and often beyond the capacity of a conventional automated production processes. Currently, most challenging multi-materials assemblies are mechanically fastened and/or adhesive bonded. Limitations associated to using these two techniques include extra weight, cost and durability issues. These drawbacks limit the adoption of more advanced multi-material joining applications and reduce potential benefits of optimised designs.Consequently, there is a clear need for new, flexible, cost-effective and rapid methods for joining dissimilar materials, capable of meeting industry performance and manufacturing demands. _ULTIMATE_ focuses on the development of an innovative technology to enable highly dissimilar materials to be fusion welded together using highly productive industrial processes. The _ULTIMATE_ project will primarily focus on dissimilar material combinations of interest to the transport sector, including dissimilar metallic materials, and composite to metallic material joints. Case studies and technology demonstrators will be produced for the aerospace and automotive sectors, although the technology has the potential to be highly versatile and applied to many different applications across other industry sectors."

“多材料组件的设计和连接在一起，以实现特定应用和特定工作环境的最佳性能。这些组件联合收割机将每种材料的优点结合到一个先进的结构中，能够在异质和恶劣的条件下工作。异种材料组件功能强大，节省材料资源，并可显著减轻重量，这是降低燃料消耗和二氧化碳排放（运输行业的主要目标）的基础。然而，将不相容的金属合金或CFRP复合材料连接到金属合金是一项挑战，通常超出了传统自动化生产工艺的能力。目前，大多数具有挑战性的多材料组件是机械紧固和/或粘合剂结合的。与使用这两种技术相关的限制包括额外的重量、成本和耐用性问题。这些缺点限制了更先进的多材料连接应用的采用，并降低了优化设计的潜在效益。因此，显然需要能够满足行业性能和制造需求的新型、灵活、经济高效和快速的异种材料连接方法。_ULTIMATE_专注于开发一种创新技术，使高度不同的材料能够使用高生产率的工业工艺熔焊在一起。ULTIMATE项目将主要关注运输行业感兴趣的异种材料组合，包括异种金属材料和复合材料与金属材料的连接。将为航空航天和汽车行业提供案例研究和技术演示，尽管该技术具有高度通用性的潜力，并适用于其他行业的许多不同应用。"
