Babcock Webinar on Failure Analysis

Webinars 10 February 2022

Babcock Exclusive Webinar: Failure Analysis 

There are many reasons behind cracking in welded assemblies. For carbon steels, these can be grouped into the metallurgical reasons; mechanical reasons and human factors. This presentation considers six of the metallurgical reasons for cracking in carbon and low alloy steels which may occur as a result of fabrication, and one with metallurgical susceptibility associated with service cracking. These metallurgical reasons can be understood and mitigated for at various stages of production and life, and are of relevance as they lead to costly repairs and rework, or catastrophic failure, if left unchecked. After the presentation, you will be aware of some of the reasons for the cracking, and how to avoid such cracking at fabrication or during service.

Continuing Professional Development 

TWI awards points towards CPD for delegates attending this webinar. Every hour attendance of a webinar will earn 2 points towards your continuing professional development.

Please contact Becki Parratt if you require a certificate of attendance towards your continuing professional development.  

Speakers

Joanna Nicholas - Team Manager, Metallurgy, Materials and Structural Integrity Group

Joanna Nicholas

Team Manager, Metallurgy, Materials and Structural Integrity Group

Joanna joined TWI in 1999, and has been involved in research, materials selection and failure investigations, mainly with ferritic steels. Joanna has also supported engineering critical assessment activities by undertaking post-test metallographic assessment on fracture toughness test specimens. She has also been involved in various aspects of computer modelling, particularly for research projects.

Joanna has broad knowledge of ferritic steels with particular emphasis on hydrogen cracking and hydrogen diffusion, HAZ hardness, mooring chain, fasteners, in-service welding and 9% Ni steels. She has carried out numerous investigations in these areas including failure investigation as well as production qualification and research. She currently serves on several BSI committees, providing welding and metallurgy input to the standards as required. Joanna lectures on the IIW/EWF diploma, and provides training and mentoring in other areas of welding metallurgy specialisms.

Joanna was awarded CEng in 2005, IWE in 2016, FWeldI in 2017 and FIMMM in 2018. Joanna is a STEM Ambassador, and delivers various activities to local schoolchildren, aiming to retain their interest in science, technology, engineering and mathematics, and was awarded the Welding Institute/Armourers and Brasiers Award for Best STEM Ambassador in 2015.
