Book Description
Fracture toughness tests of deep-notched and shallow-notched SENB specimens at various sub-zero temperatures were conducted to study the effect of weld metal mismatch on measured fracture toughness. Tensile tests of cross-weld tensile specimens were also conducted to study the effect of weld metal mismatch on joint efficiency. These specimens were machined from butt welds that were fabricated with the same welding consumable and welding procedure using HSLA 100 steel plates heat treated to different tensile strengths. No significant differences were found between the joint efficiencies and ductilities of the cross-weld tensile specimens with overmatching weld metal and those of specimens with up to 9% weld metal undermatch in terms of yield strength (3% in terms of ultimate tensile strength). Furthermore, 100% joint efficiency was still achieved in the cross-weld tensile specimens with intact reinforcements and 17% undermatching weld metal in terms of yield strength (9% in terms of ultimate tensile strength). No correlation was found between the degree of weld metal mismatch and the measured fracture toughness of the SENB specimens.

Dynamic Fracture Toughness Characterization of HY-100 Under-Matched Welds

Pages : 92
Book Description
Welds in marine structures are typically fabricated such that the yield strength of the weld metal is higher than the base plate (over-matched). Allowing the weld metal yield strength to be less than the base metal (under- matching) can increase productivity and weld metal toughness; however, there is some concern that under-matching increases the crack driving force and decreases the weld metal tearing resistance. This study examined fracture behavior of two HY-100 under-matched welds under dynamic loading. A new test fixture that provided greater control of specimen deflection during impact testing of SE(B) specimens was developed, as was a procedure for applying the Normalization Method to the analysis of dynamic fracture toughness tests. Successful application of Normalization involved using multiple specimens with varying ductile crack growth to establish the correct form for the plasticity function. The accuracy of the measured J(sub Id) was verified by comparing with multi- specimen J(sub Id) values. The results from these tests showed that the proximity of the crack tip to the fusion line had more effect on fracture behavior than mismatch level. Narrower fusion line margins led to lower tearing resistance and a greater propensity for fracture instability.
