WebJul 6, 2008 · ABSTRACT. High strength line pipe steels needs to have good crack arrestability to arrest cracks in the pipe body even if brittle fracture occurs at welds, or running ductile fractures occur in the pipe body. The drop weight tear test (DWTT) is one of the major test methods to evaluate crack arrestability of brittle and running ductile … WebMay 22, 2003 · Priyasachin, dear friend, one more reason of DWTT is: whereas the standard V notch impact test is conducted on fully machined bar of 10x10mm or smaller, it is certain that the surface condition of the mother plate or product does not get reflected in the test. in DWTT the sample is much wider, a crack starter is introduced, and the surface …
