Six points (P1, P2, P3, P4, P5, and P6), three in each side of the bead weld, were fixed to measure the microhardness, as shown in Figure 2.
So, we can conclude that hardness decreases from the region near the bead weld toward the edge of the part.
The microstructure of the weld metal cap pass was analysed with electron backscattered diffraction (EBSD) in a FEI Quanta 450 scanning electron microscopy with Bruker [e.sup.-] Flash model with 20 kV, steps sizes of 11.93 and 0.46 [micro]m, for overall last
bead weld metal and the superficial layer, respectively.
The narrow face and aggressive knots are perfect for cleaning stringer
bead welds. In addition, brushes can be mounted both vertically and horizontally and are compatible with a wide variety of popular hand-held and bench grinder tools.
