Abstract: Continuous research is carried out in the automotive
industry to decrease the weight of automobile bodies without reducing
durability. For this purpose, the use of welding sheet metal is one of
the successful techniques. Welded sheets are formed by combining two or
more flat materials with different thicknesses and different mechanical
properties, using the welding method, before being shaped in order to
provide superior properties. This situation requires more attention
during the shaping stages. It is important to calculate the pressures to
be applied to the welding areas and to apply the shaping steps in a way
that will not reduce the material strength. For this reason, the
production stages of the dies to be used in the manufacture of these
parts are just as important. In this study, an innovative die design is
carried out for the production of welded sheet metal. The microstructure
and mechanical properties of the welded sheet formed by the die were
examined. The effect of the forces applied to the welding areas on the
material and the mechanical properties of the materials of different
thicknesses were determined. Within the scope of the study,
microstructure analysis, hardness and tensile tests were carried out and
the results were examined. When the results obtained were examined, it
was seen that the strength and hardness values of the samples obtained
from the welded area were higher than the other areas.
Keywords:
welded sheet, mechanical property, microstructure, steel, die
technology.
