Synergic regimes optimisation of pulsed mig arc welding

Abstract

Because of the advantages offered, Pulsed MIG arc welding is used in recently years with an increasing frequency, for a large number of welded products in the Romanian industry. Welding sources parks were replaced gradually with new modern sources during 2000-2009. To extend the domains of use and adaptation of the welding regimes for synergic pulsed MIG welding were required numerous experimental determinations. This paper aims to find and validate an optimal welding regime for "pulse-drop" welding transfer, other than those set by manufacturers, in order to flexible use of the sources from earlier generations. To carry out the experiments a complex computerized system for data acquisition and high-speed shooting system was used.
