| Summary: | The main objective of this paper was to establish how the thickness of welded pieces influences the metallographic structure of welded joints. Thus were made a total of 6 samples, and from each sample were taken test specimens for metallographic analysis of the base material, the filler material respective heat affected zone (HAZ). The samples were carried out by welding process: metal active gases (MAG) using a steel E 36-4, and the welded pieces had a thickness between 10 and 24 mm. The welding regime was characterized by parameters I<sub>w</sub> = 200 / A, Uw = 24 / V. The joint by welding pieces was “T” form and both piece used as the base and the piece used as heart for welded joint were made of sheets with different thicknesses. |
