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：该博士项目将在不同的材料连接区域（即钢制到铝制结构）中产生知识，并具有远程激光焊接（RLW）工艺。在项目期间，我们将研究金属间化合物的形成，以实现结构应用的持久连接。挑战的规模：由于其高生产吞吐量和灵活性，在汽车行业中，RLW越来越多地被采用准确，并减少热量影响区域。我们已经验证了铝板的加入；我们正在通过验证铝制铸件和挤出量来进行结构应用。连接不同的金属（钢与铝结构）是下一个挑战。缺乏对正确的金属间化合物（IMC）的有效控制，该化合物（IMC）将实现耐用的连接是一个限制因素，从而阻止了该技术在大众生产中的全部吸收，尤其是对于结构应用。该项目将不得不克服这一挑战，以确保正确实施RLW流程以在未来的计划中进行不同的金属。目的：该博士学位项目的具体目标是：查看现有的方法/技术解决方案，以控制IMC形成以开发新方法（焊接技术）来控制IMC形成，以与CAE模拟相辅相成，以预测金属混合，通常无法直接测量实验验证和验证和验证，提出的具有相关材料的方法（根据JLR的输入进行完善的合金和核心应用）适合EPSRC和国家工业战略：该项目直接解决了ESPRC主题“制造未来”。它还直接为ESPRC研究领域（例如制造技术和材料工程）做出了贡献。该项目还将支持英国政府的“零之路”战略和英国政府在2020年11月发起的“ 10点计划”，并通过解决轻型车辆和电子机动性，以及通过加速他们对市场介绍的加速。专注于降低成本，可靠性和安全性，同时加快零缺失和零浪费的策略，并增加采用回收材料。
