fracture toughness has become a vital factor in the field of fracture mechanics. As welded joints are subjected to high thermal stresses and external loads, the strength of the weld will be much different than the actual parent material. A small external crack in the welded joint will cause the failure in the Fracture and Fatigue of Welded Joints and Structures - 1st Apr 19, 2011 · The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents.

    Weld Strength Mismatch and HAZ Fracture Toughness

    • AbstractIntroductionExperimental DetailsResults and DiscussionThe effect of weld metal strength mismatch on the fracture toughness of the weld heat affected zone (HAZ) in two ferritic steels is described. Mismatch was achieved in two different ways which ensured that the HAZs were the same, irrespective of mismatch level. It is shown that fracture toughness is more affected by the local strength of the HAZ rather than differences in strength between weld metal and parent plate. Where HAZ strength is lower than both the parent plate and weld metal, HAZ fracture toWeldability and weld joint failures - iasWeldability and weld joint failures 215 (c) High heat input (electroslag, electrogas etc.) 10 to 40 kJ/mm.
