Document Type and Number:

Japanese Patent JP5612844

Kind Code:

B2

Abstract:

System and method for determining a susceptibility of a sample (26) of material, which includes a welded area (20), to reheat cracking. The method includes measuring a length of the sample (26), applying a first stress to the sample (26) to achieve a predetermined elongation of the sample (26), exposing the elongated sample (26) to a predefined heat treatment, applying a second stress to the sample (26) until the sample breaks at least into two different pieces (30, 40), and determining the susceptibility of the broken sample (26) to reheat cracking.
