From: Initiation and growth kinetics of solidification cracking during welding of steel
3D tomographic reconstruction and characterisation of weld solidification cracks, showing: (a) macrograph of the sample weld containing solidification cracks, (b) 3D reconstruction of the crack containing volume. The weld and some solidification cracks are visible on the top surface. The yellow arrows denote the Cartesian coordinate system for view plane reference, (c) Y-Z plane 2D view of the solidification crack network. The blue box represents a “mature” solidification crack that is fully grown. The red box represents “infant” solidification cracks that are primarily sub-surface and invisible from visual inspection of Fig. 3(a,d) X-Z plane view of the solidification crack network showing somewhat symmetric features in terms of the angle of cracking either side of the weld centreline due to the symmetrical nature of the weld itself.
