Eskom Webinar on FEA - In-situ PWHT of pressure vessels

Webinars 04 March 2026

Eskom Webinar on FEA - In-situ post-weld heat-treatment of pressure vessels and related structural stability 

Time: 1pm, South Africa/11am, UK

TWI will present an overview on the use of Finite Element Analysis (FEA) for designing and evaluating in-situ post-weld heat-treatment of pressure vessels for engineering applications. The aim is to provide a summary of how FEA can be used effectively to support the development of suitable local heat treatment regimes and numerically demonstrate meeting code or design requirements. Assessing the implications for local stress and deformation behaviour will also be discussed. 

Speakers

Michael Roy - Chief Finite Analyst, Numerical Modelling and Optimisation

Michael Roy

Chief Finite Analyst, Numerical Modelling and Optimisation

Michael provides finite element analysis and manufacturing process simulations to advise TWI Members on questions related to structural integrity, weld distortion control and thermal management. Before joining TWI, he worked in the ship structures group at QinetiQ, and subsequently in the oil and gas industry where he performed nonlinear structural, thermal and dynamic analysis and design assessment of subsea equipment. Michael is a member of the panel IIW Commission X on fatigue modelling and residual stress, and he holds an MEng in Mechanical Engineering from the University of Strathclyde and a PhD in fatigue crack modelling from Heriot-Watt University.
