FINITE ELEMENT ANALYSIS OF LASER BEAM SPOT WELDING OF ALUMINUM (2014-0)

Abstract

In this paper, an axis-symmetric finite element  (F.E.A.) model for the resistance spot welding (RSW) of aluminum 2014-o is developed using the (F.E.A.) software ANSYS(11). It accounts for the interactions of mechanical, thermal phenomena.

The (F.E.A.) is accomplished through the laser beam contact characteristics and thermal effects of Aluminum due to being heated to a high temperature.  The phase change due to melting is accounted for a very small area near the laser spot. At the same time, temperature-dependent variable material properties are used for the simulation. In addition shear stress and strain distribution were calculated with a comparison with experimental work of recent studies.
