Join us at Cranfield for a talk and guided tour of the Welding Engineering and Laser Processing Centre - a chance to see around the laboratory and hear from the researchers' ongoing cutting edge work in WAAM.
If your supply chain is hindered by the long lead of forgings and you want something quicker; if you want a more environmental manufacturing process that reduces the need for transportation of large heavy forgings across Europe, and reduce the quantity of coolant and oil contaminated swarf from machining; if you are looking for better material properties than a forging and the possibility of a reduction in cost for exotic material, then you need to find out more about Wire + Arc Additive Manufacturing (WAAM) of large scale net shape parts
WAAM was mentioned in the IMechE Professional Engineering magazine's 15 January 2019 issue in an article entitled ‘Additive manufacturing goes large – aerospace prints bigger and better parts’.
Come and join us at Cranfield University for a tour of the Welding Engineering and Laser Processing Centre and to hear more from researchers about their work in the field of Wire + Arc Additive Manufacturing (WAAM), and see in the laboratory a 6m aluminium spar, one of the biggest parts ever produced by additive manufacturing. This is an update of the technology and ongoing research from the last IMechE event held back in February 2017.
The combination of an electric arc and wire feedstock is referred to as Wire + Arc Additive Manufacturing (WAAM). Additive Manufacturing (AM) is a technology that promises to revolutionise manufacturing by reducing material wastage and overall time to market. Furthermore, AM can also enable an increase in design freedom, potentially realising weight savings through the manufacture of complex single components which previously required assemblies of many subcomponents for manufacturability.
WAAM combines an electric arc (as a heat source) and wire (as feedstock) to produce physical components. Whilst the first patent for WAAM was filed in the 1925, WAAM has been seriously investigated as a viable AM technique since the 1990s.
WAAM hardware currently uses standard, off-the-shelf welding equipment: welding power source, torches and wire feeding systems with motion provided by robotic systems or CNC gantries.
This event comprises a tour of the Cranfield University Welding Engineering and Laser Processing Centre with short talks from researchers in the field.

Dr Filomeno Martina - Lecturer in Additive Manufacture
Programme Manager, Titanium Development
Filomeno is the CEO of WAAM3D and a lecturer in Additive Manufacture in the Welding Engineering and Laser Processing Centre, Cranfield University, where he is contributing to the research and developing Wire + Arc Additive Manufacturing (WAAM). He received his PhD in Additive Manufacturing from Cranfield in 2014; the main focus of his doctoral research was the manipulation of the geometry, microstructure and mechanical properties of large WAAM titanium deposits. Previously he earned an MSc from Cranfield and an MEng in Industrial and Management Engineering from Polytechnic of Bari (Italy).
Dr Eloise Eimer - Research Fellow
Integrated Aluminium Structures
Eloise is a PhD research fellow working within the Welding Engineering and Laser Processing Centre at Cranfield University. She recently graduated from Cranfield with her doctorate , having completed her international internship funded by Constellium. Her work is focused on aluminium, especially dissimilar aluminium WAAM parts and development of high strength aluminium.
Prior to this Eloise worked at the Constellium Technology Centre (C-TEC)and Issoire production plant on thermomechanical simulation of spray quenching and on the experimental set up of a new industrial quenching machine.
Leonor Neto - PhD Research Student
Application of Machine Hammer Peening for Wire + Arc Additive Manufacture Properties Improvement
Leo is a second year PhD student in the Welding Engineering and Laser Processing Centre (WELPC) at Cranfield University. The main focus of his ongoing research is in the application of machine hammer peening to improve WAAM deposit properties. Prior to this he studied Mechanical Engineering at Instituto Superior Técnico Portugal.
Philippe Bridgeman - PhD Research Student
Plasma Arc Welding Torch Optimisation and Torch Arc Pressure Measurement
Philippe is a third year PhD student researcher at Cranfield's Welding Engineering and Laser Processing Centre (WELPC), sponsored by Airbus to undertake a long-term personal goal of completing a PhD in Manufacturing in a cutting edge manufacturing process - WAAM. He is a UK and Europe Chartered Mechanical Engineer with over 14 years of oil and gas industry experience, having worked in the UK, Australia and across Europe. He is also an IMechE Fellow, Member of TWI, Chair of the Bedfordshire IMechE Panel, and active member of the IMechE Oil, Gas and Chemical Committee, with a real passion for engineering. He holds a BEng (Hons) in Mechanical Engineering from RGU and an MSc in Welding Engineering (Welding & Metallurgy) from Cranfield University.
Guangyu Chen - PhD Research Student
Calorimetry Experiments and Finite Element Modelling for Multi-Energy Source in the NEWAM
Guangyu Chen is a second year PhD student who manily focuses on calorimetry experiments and finite element modelling for multi-energy sources in the NEWAM project. This involves measuring the energy distributions of different heat sources to provide data basics for numerical simulations, and developing a general FE modelling method for different forms of MES.
Guangyu is from China. He achieved his master’s degree from Harbin Engineering University and his undergraduate from Tianjin University. Although his previous major was Navel and Ocean Engineering, his supervisor during the master's was interested in the welding technique for large scale ship structure, which is how he started to study welding.
Chong Wang - PhD Research Student
Deposition of Titanium Alloy with Laser and Plasma Arc Hybrid Process
Chong Wang is a second year PhD student in the Welding Engineering and Laser Processing Centre (WELPC) at Cranfield University. Prior to this, he obtained his MSc and BSc degrees both from China University of Petroleum (East China) between 2010 and 2017, specialising in Mechanical Engineering. His role on NEWAM programme is primarily focused on increasing the deposition rate of titanium alloy with laser and plasma arc hybrid process. In this procedure, he will first investigate the limitation of deposition rate by using a single plasma power source, and then he will study how to further increase the deposition rate as well as how to control the bead shape with laser and plasma arc hybrid configuration.
Dr Ginarocco Marinelli - Research Fellow
Gianrocco is a Postdoctoral Research Fellow at the Welding Engineering and Laser Processing Centre, Cranfield University, where he was awarded the Doctor of Philosophy degree for his research in the field of additive manufacturing in 2018.
He developed the Wire + Arc Additive Manufacturing (WAAM) process for refractory metals, such as unalloyed tungsten, tantalum and molybdenum, for high-temperature applications. Furthermore, he successfully developed a controlled procedure to generate functionally graded structures in refractory metals via WAAM. Previously, he studied Materials Science at the University of Bari, Italy. Currently, his role is to manage multiple projects dedicated to both academic research and additive manufacturing component production. Furthermore, he has considerable experience in estimating cost, designing tooling and generating robotic routines for the production of unique AM component deposited via WAAM.
