Models

Abstract
Welding is an operation with a complex character involving a multitude of
physical phenomena which are mostly extremely non-linear and transient.
Today's commercial multi-purpose programs provide powerful tools for
the simulation of transport problems. However, their general models
cannot cover all essential physical effects, especially those occurring in the
domain of the molten pool. A promising way to overcome this situation
is the implementation of specialised micro-models in existing codes. With
that the field of application of both micro- and macro-model can be
widened. This paper is focused on the coupling of specialised models
for the region around a concentrated moving heat source with a code for
the prediction of the effects occurring in the base metal. As an exampl
