Summary
This paper, Part III in this series on wide-plate testing of weldments, reviews the latest developments in wide-plate test procedures used for evaluation of the heat-affected zone (HAZ) toughness in steel weldments. In particular, emphasis is placed on the transversely loaded wide-plate test specimen in which the orientation of both the crack and the weld is transverse to the loading direction. This wide-plate test configuration is often conducted to evaluate the structural significance of low HAZ CTOD values. To this end, fatigue-precracked surface-notched wide-plate specimen tests are employed to assess this specific local brittle zone (LBZ) problem. The need for sectioning the wide-plate specimen after testing to identify whether the intended microstructures have been sampled is discussed, and examples are given to illustrate the type of information which is currently produced.
