EWI principal engineer in modeling and simulation Yu-Ping Yang was recently published in Materials and Design.
In the November 2015 issue, Effect of humidity on porosity, microstructure, and fatigue strength of A7N01S-T5 aluminum alloy welded joints in high-speed trains, the authors addressed humidity and its impact on the quality of welded joints for high-speed trains. Welded joints made of A7N01S-T5 aluminum alloy were fabricated under five relative environmental humidity conditions: 50%, 60%, 70%, 80%, and 90%. Read the article to find out what these researchers determined to be the critical humidity level for welding joints in high humidity environment.
