Abstract :
In this paper, we present a discrete contour model used to follow the dynamical behaviour of a molten metal bridge in short arc welding. Good results are achieved on experimental movies as bridge edges are well detected. This approach enables the estimation of the relevant variables in the establishment of a model of MIG/MAG welding in short arc mode.
