DOWNLOAD EBOOKThe usual fracture mechanics based concepts available to assess structural integrity have been developed for homogeneous structures. When considering cracks in welds, these methods assume that cracks are located in a material of uniform properties and neglect any difference of strain carrying capacity due to mismatching effects. The French Cracked Weld Research Programme (FCWRP, conducted by CEA, EDF, and FRAMATOME) has been in progress for the last three years to investigate how the effects of weld metal mismatch may affect structural resistance of welded structures. This paper gives an overview of the conclusions and results drawn from this program.

DOWNLOAD EBOOKThe combination of distinct materials is a key issue in modern industry, whereas the driving concept is to design parts with the right material in the right place. In this framework, a great deal of attention is directed towards dissimilar welding and joining technologies. In the automotive sector, for instance, the concept of “tailored blanks”, introduced in the last decade, has further highlighted the necessity to weld dissimilar materials. As far as the aeronautic field is concerned, most structures are built combining very different materials and alloys, in order to match lightweight and structural performance requirements. In this framework, the application of fusion welding techniques, namely, tungsten inert gas or laser welding, is quite challenging due to the difference in physical properties, in particular the melting point, between adjoining materials. On the other hand, solid-state welding methods, such as the friction stir welding as well as linear friction welding processes, have already proved to be capable of manufacturing sound Al-Cu, Al-Ti, Al-SS, and Al-Mg joints, to cite but a few. Recently, promising results have also been obtained using hybrid methods. Considering the novelty of the topic, many relevant issues are still open, and many research groups are continuously publishing valuable results. The aim of this book is to finalize the latest contributions on this topic.

DOWNLOAD EBOOKFracture 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.
