The preliminary results indicate that, despite the lower properties revealed in the weld metal by the micro tensile tests, cracking does not systematically occur in this region. Instead, a competition between the mechanical properties, the weld geometry, and the amount of additional material deposited plays a decisive role in determining the crack initiation site. These multiaxial tests will also be instrumented using Stereo DIC in order to highlight the most critically loaded zones.
