Personal statement

Dr Yashar Javadi is a Strathclyde Chancellor’s Fellow (Lecturer as part ‎of Strathclyde Global Talent Programme) at the University of Strathclyde. His ‎multidisciplinary works have been reflected in his appointment which is a joint ‎appointment between two departments (EEE and DMEM). He is currently ‎Guest Editor of "Welding and Additive Manufacturing for Industry 4.0", a ‎special issue of "Journal of Manufacturing and Material Processing", and also in ‎the Topic Board of that journal. He is also editor of Special Issue "Robotic Non-‎Destructive Testing" in Sensors.‎ In a career spanning over 16 years in the field of engineering (particular focus ‎on welding, non-destructive evaluation, additive manufacturing and robotics), ‎he has worked as a lecturer and postdoctoral ‎research associate (at The ‎University of Manchester and the University of Strathclyde) in the academia ‎and also a manager of the welding/NDT department and welding engineer in ‎the industry. He has published ‎‎>40 journal papers with >1000 citations in total, ‎including two ‎papers with >100 ‎citations.‎ Currently, he is a member of Centre for Ultrasonic Engineering (CUE) where his ‎research focus is on the in-process inspection and residual stress measurement ‎‎(non-destructive methods) in the welding and Wire + Arc Additive ‎Manufacturing (WAAM). Some part of his current research outputs is reflected ‎in two WAAM/NDT papers published in Insight (2018) and Additive ‎Manufacturing (2019) journals plus two Welding/NDT papers recently ‎published (2020) in Materials & Design (in-process calibration) and Journal of ‎Manufacturing Processes (residual stress).‎ ‎* Open PhD positions (please email me for details):‎ ‎1) In-process calibration of a robotic NDE system used for high-temperature in-‎process inspection ‎2) In-process Material Evaluation of Welding and Additive Manufacturing ‎3) Non-destructive Evaluation of Residual Stress

Residual stress measurement round robin on a wire arc additively manufactured titanium alloy
Javadi, Yashar (Principal Investigator) Sun, Yongle (Co-investigator) Alipooramirabad, Houman (Co-investigator) MacLeod, Charles Norman (Co-investigator) Reid, Mark (Co-investigator)
The aim of this project is the development of a round-robin residual stress measurement to investigate the residual stress in ‎titanium (Ti–6Al–4V) Wire + Arc Additive Manufacture (WAAM) ‎components. Cranfield will contribute with the manufacturing and finite element modelling of the WAAM samples. ‎ANSTO is supporting the project with residual stress measurement using Neutron Diffraction (ND) method‎.

Investigating the effect of residual stress on hydrogen cracking in multi-pass robotic welding and additive manufacturing
Javadi, Yashar (Principal Investigator) MacLeod, Charles Norman (Co-investigator) Alipooramirabad, Houman (Co-investigator)
The aim of this project is the development of a round-robin Residual Stress (RS) measurement to investigate the effect of the ‎RS on hydrogen cracking. ‎Dr Javadi ‎(PI) is leading the RS area in the Center for Ultrasonic Engineering (CUE) and he has been a Keynote Speaker at ‎the 11th International Conference on Residual Stress (ICRS 11) where he presented his novel idea on RS ‎measurement using the Phased Array Ultrasonic Testing (PAUT) method [1]. This method will also be used ‎to study the effect of RS on hydrogen cracking. In this Strathclyde-ANSTO collaboration, ANSTO will conduct the Neutron ‎Diffraction (ND) to form the round-robin RS measurement project. ‎

Robotic Ultrasonic System for In-situ Residual Stress Measurement in Metal ‎Additive Manufacturing
Walker, Joseph (Post Grad Student) Javadi, Yashar (Principal Investigator) Heidari, Hadi (Co-investigator) Rahimi, Salaheddin (Co-investigator)
Residual Stress (RS) in engineering components yields unexpected and dangerous structural ‎failures, and thus ‎represents a significant challenge to quality assurance in both welding and metal ‎Additive Manufacturing ‎‎(AM) processes. As automation in welding and AM becomes increasingly ‎prevalent in the Industry 4.0 ‎manufacturing paradigm, so the importance of quantifying RS will ‎grow. In this PhD project, a novel robotic ‎ultrasonic approach to measuring such RS, in-situ, will be developed using the Phased Array Ultrasonic Testing ‎‎(PAUT) system, to automate the deployment of the ‎measurement in manufacturing applications. For the first ‎time, it will allow truly in-situ ‎measurements of RS to be undertaken at the elevated temperatures associated ‎with welding and ‎metal AM manufacture. The ambition is to use this in-situ measurement system for safety-‎critical and Industry 4.0 applications, through 5G wireless integration of the robotic system, where the ‎conventional manual and destructive methods of RS ‎measurement are not applicable for high throughput and ‎automated production lines.‎
