Abstract
Formation of a solidified joint between metallic and/or non-metallic materials is a critical phase of a manufacturing process called brazing. This paper provides an insight into an important aspect of this complex joint formation process for a system of aluminum alloys AA4343-AA3003 plus KF-AlF3 as a flux. More specifically, a proof of the validity of the following hypothesis is given: the topology of the solidified brazed aluminum alloy joint can efficiently be described by an equilibrium membrane of the liquid alloy at the onset of solidification. A controlled atmosphere aluminum brazing process was considered. An experimental procedure is performed with ultra-pure nitrogen. Numerical results, based on a finite element discretization of a 2-D membrane profile, were obtained utilizing the minimum potential energy principle. An excellent agreement between theoretical predictions and experimental data unequivocally proves the validity of the introduced hypothesis.
