Measurement and modelling of residual stresses in thick section type 316 stainless steel welds

Key Points

• Residual stresses are critical in understanding the integrity of thick section stainless steel welds, and affect performance and durability.
• Significant variations in residual stresses were measured using advanced modeling techniques across different weld sections.
• Assessment using a combination of experimental measurements and computational modeling indicated complex stress distributions in the welds.
• This analysis may enable improved design practices and maintenance strategies in structural steelwork, ensuring safety and reliability.
