Re: [MW:7961] purpose of doing nick-break test.

Dear Mr Baskaran,

This test is performed to reveal internal imperfections such as slag inclusion, lack of fusion, incomplete penetration, porosity, etc in a butt weld.  A butt weld specimen is fractured along an artificial notch that is intentionally machined on the centre line of the fillet weld specimen to facilitate fracture in the centre of the weld. The fractured specimen cross section is then visually examined for imperfections.
