WebMay 19, 2024 · Due to the higher bond strength at the weld, the weld that had not yet fractured at the aluminum base material in the shear process fractured, resulting in the adhesion of aluminum on the welded joint.As shown in Fig. 9c, the fracture showed obvious brittle fracture characteristics. The fracture along the thickness direction mainly … WebOct 5, 2006 · The above results show that this test could only differentiate welds containing talc contamination, all of which failed in a mainly brittle manner through the weld interface (see Fig.4). All other specimens either failed in a fully ductile manner through the plane of the heating wires ( Fig.5) or through the pipe ( Fig.6).
