Metallurgy and Cracking Mechanisms (online event)

What will the event cover?

Metallurgy and Cracking Mechanisms.  There are many reasons cracking in welded assemblies.  For carbon steels, these can be grouped into the metallurgical reasons, mechanical reasons, and human factors.

What will you learn? 

This presentation considers 6 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 if production and life, and are of relevance as they lead yo 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.

Meet the speaker: 

Joanna joined TWI Ltd in 1999, and has been involved in research, materials selection, and failure investigations, mainly with ferritic steels, alongside welding consultancy.  She has also been involved in various aspects of computer modelling of weld phenomena and welding software supporting standardisation of weld procedures and welder qualifications.

Joanna has a broad knowledge of ferritic steels with particular emphasis on hydrogen cracking and hydrogen diffusion, HAZ hardness, mooring chains, 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.
