In this episode, Cathleen Shargay, Advisor of Materials and Welding Engineering at Becht, joins co-hosts Heather Allain and Marc Cook to explore the complexities of materials selection during project execution. The conversation covers a wide range of essential topics, from understanding what materials selection diagrams (MSDs) are and how they interface with process engineering, to evaluating life cycle cost inputs and establishing design life. Cathleen also unpacks how MSDs relate to Integrity Operating Windows (IOWs) and Corrosion Control Documents (CCDs), and how these tools work together to support informed decision-making. The episode dives into strategies for managing excursions, assessing corrosion circuits, and understanding the consequences of material failure. Finally, the discussion looks ahead to how artificial intelligence is beginning to shape materials selection and analysis in the future of engineering.

In this episode, Ana Benz, Chief Engineer at IRISNDT, joins co-hosts Heather Allain and Marc Cook for a deep dive into selecting non-destructive examination (NDE) techniques based on expected damage mechanisms. Ana shares insights on recent advancements in radiography, field-based hardness testing, and imaging of hardness indents to assess effectiveness. The conversation also explores proper surface cleaning for inspections, the use of chemical composition analysis to detect degradation from galvanic corrosion, and the role of Integrity Operating Windows (IOWs). Additional topics include remote monitoring applications and innovations in remote inspection technology.
