Abstract
The effect of the straining rate and the augmented-strain on the length of solidification crack occurred in the weld metal has been investigated theoretically and experimentally by means of the Slow Bending Speed (SB) Trans-Varestraint cracking test for four aluminum alloys, that is, 5052-o, 5154-o, 5083-o and 2017-o. For the prediction of the crack length occurred in the weld metal, the equations was theoretically derived under some assumptions. As a result of comparing the calculated values of the crack length with the actual values, it was proved that there was a good agreement between them.
