Estudio de la influencia del stick out en las propiedades mecánicas del acero a 36, soldado mediante los procesos de unión FCAW-SS y FCAW-GS.

Abstract

The purpose of this research work is to study the influence of stick out in the FCAW flux cored arc welding process when welding beads on A36 steel plates with different amperage and voltage values, in order to identify the incidence of these parameters in welded joints. With the help of catalogs and codes such as AWS D1.1, it is possible to identify a n d e sta b lish recommendations for a correct application of the Innershield and Outershield welding process on A36 steels mo stly u se d in metallic structures. The analysis has relevance due to the fact that the investigated bibliograph y does not provide sufficient information that evaluates the influence of the distance between the contact tip and the electrode tip (stick-out) on the mechanical properties of the weld bead when the joining processes are used. The purpose is to aid future investigations of the incidence of variables on weld beads and will serve as a guide fo r p ra ctica l applications in the daily work performed by welders in the construction industry.
