Particularidades de la transferencia metálica y la aplicación de corriente pulsada en soldadura submarina

Abstract

In this work, the types of metallic transfer present in electric arc welding with tubular wire and the main characteristics of the pulsed current technique applied in underwater wet welding are exposed. For this, it was essential to collect and analyze the information from different investigations, condensed into technical-scientific articles. This document is divided into two sections: first, the effect that the parameters and conditions of the process have on the type of metal transfer is elucidated. In addition, the application of the pulsed current is presented, and its effect on the control of the size of the metal drops, as well as its frequency and mode of detachment from the electrode to the weld pool.
