Abstract
This paper is focused on welding with a consumable electrode in a gas shield atmosphere
and its main aim is to show the influence of selected processes and technological parameters on the
geometry of the weld pool in terms of theoretical and experimental views. For this purpose, the
parametric areas defined by the change of the welding current and welding rate were determined.
Apart from the influence of these parametric areas, the influence of other technological input variables,
including the wire diameter and preheating temperature, was also studied. The experimentally obtained
geometric data of the weld pool can be used for technological welding procedures WPS and especially
for simulation calculations to obtain a more accurate numerical model of the heat source. This makes
it possible to get accurate simulation results and to better understand the impact of other variables
that influence the welding process. This all helps to the optimization of the welding process for several
applications
