Abstract: The effect of strength differences (mismatch) between weld metal and two base metals as well as local variations of strength within weld metal/HAZ zones on the toughness properties were discussed. The significance of local fracture toughness measurement technique was also discussed by comparing the CTOD results of [delta]5 and British Standard [delta]BS. Some differences between the two techniqes were discussed in particular for CGHAZ toughness of similar and dissimilar joints.Keywords: welding, welded joints, fracture mechanics, HSLA steels, fracture toughnessPublished in DKUM: 10.07.2015; Views: 1514; Downloads: 49 Link to full text
