Project aim: this PhD project will generate knowledge in the area of dissimilar material joining (i.e., steel to aluminium structures) with Remote Laser Welding (RLW) process. During the project we will study the formation of intermetallic compounds to enable a durable join for structural applications.Scale of challenge: RLW is increasingly being adopted within the automotive industry due to its high production throughput and flexibility, making the welding process much faster and more accurate, with reduced heat affected zones. We have already validated the joining of aluminium sheets; and we are working through the validation of aluminium castings and extrusions, for structural applications. Joining of dissimilar metals (steel to aluminium structures) is the next challenge. The lack of efficient control of right intermetallic compound (IMC) that will enable a durable join is a limiting factor preventing the full uptake of this technology in mass production, especially for structural applications. The project will have to overcome that challenge to ensure the right implementation of RLW process to dissimilar metals in future programs. Objectives: specific objectives of this PhD project are:Review existing methods/technological solutions to control IMC formationTo develop novel methods (welding techniques) to control IMC formationTo complement experimental investigation with CAE simulation to predict metal mixing, typically not directly measurable with experimentsVerification and validation of proposed methods with relevant materials (alloys and core applications to be refined based on JLR's input)Fit to EPSRC and national industrial strategy: the project directly addresses the ESPRC theme "Manufacturing the Future". It also directly contributes to ESPRC research areas such as Manufacturing Technologies and Materials Engineering. The project will also support the UK Government "Road to Zero" strategy and the "10 Point Plan" launched by the UK government in November 2020 by addressing lightweight vehicles and e-mobility, as well as by speeding up their introduction to the market with focus on cost reduction and increased reliability and safety, whilst accelerating strategies for zero-defect and zero-waste as well as increasing the adoption of recycled materials.

项目目标：该博士项目将产生异种材料连接领域的知识（即，采用远程激光焊接（RLW）工艺，可将钢结构焊接到铝结构上。在该项目中，我们将研究金属间化合物的形成，以实现结构应用中的耐用连接。挑战规模：RLW由于其高生产能力和灵活性，使焊接过程更快，更精确，减少热影响区，越来越多地被汽车行业采用。我们已经验证了铝板的连接;我们正在验证用于结构应用的铝铸件和挤压件。异种金属的连接（钢与铝结构）是下一个挑战。缺乏对合适的金属间化合物（IMC）的有效控制是阻碍该技术在大规模生产中充分应用的一个限制因素，特别是对于结构应用。该项目将不得不克服这一挑战，以确保在未来的项目中正确实施RLW工艺。目的：该博士项目的具体目标是：审查现有的方法/技术解决方案，以控制IMC的形成开发新的方法（焊接技术），以控制IMC的形成补充实验研究与CAE模拟，以预测金属混合，通常不能直接测量与实验验证和相关材料（合金和核心应用程序的验证和确认建议的方法将根据捷豹路虎的输入细化）适合EPSRC和国家工业战略：该项目直接解决ESPRC主题“制造未来”。它还直接有助于ESPRC的研究领域，如制造技术和材料工程。该项目还将支持英国政府的“零排放之路”战略和英国政府于2020年11月推出的“10点计划”，解决轻量化车辆和电动汽车问题，并加快其推向市场，重点是降低成本，提高可靠性和安全性。同时加快零缺陷和零浪费的战略，并增加回收材料的采用。
