ULTIMATE - Unconvensional Laser joining Technology for multI-MATErial products

“多材料组件被设计并连接在一起，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。不同的材料组件功能强大，节省了材料资源，并显著减轻了重量，这是打破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，将冶金不相容的金属合金或CFRP复合材料与金属合金结合是具有挑战性的，通常超出了传统自动化生产工艺的能力。目前，最具挑战性的多材料组件是机械紧固和/或粘合剂粘合。使用这两种技术的局限性包括额外的重量、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好处。因此，显然需要新的、灵活的、具有成本效益的和快速的方法来连接不同的材料，能够满足工业性能和制造需求。_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效的工业工艺融合焊接在一起。ultimate_项目将主要集中于运输部门感兴趣的不同材料组合，包括不同金属材料和金属材料接头的复合材料。案例研究和技术演示将用于航空航天和汽车领域，尽管该技术具有高度通用性，并应用于其他行业领域的许多不同应用的潜力。”

"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."
