Metallographic Test:

To investigate the structure of the base metal and weld metal, after the process of preparing mounted samples, metallographic test of welded rebars was done.

In this test complete joining of rebar was observed.

The structure of the base metal and weld metal is composed of ferrite and pearlite. Heat affected zone consists of three following areas: coarse grain, recrystallized area (the fine grain) and the tempered area, and structure of all these areas is composed of pearlite and ferrite.
