Article Synopsis
- The integrity of welded joints is crucial for the safety and reliability of welded structures, making it essential to evaluate their performance, especially in challenging environments.
- This study focuses on assessing the fracture properties of a Q235 steel butt-welded joint using two methods: boundary effect modelling (BEM) and ball indentation (BI).
- Results show that both methods provide consistent findings about fracture toughness across different zones of the weld, with the weld metal being the strongest and the fusion zone being the weakest, although there are some relative errors that suggest caution should be exercised when using the BI method for in-service structures.
