Soldadura con electrodo revestido (SMAW)

Abstract

The SMAW welding system (Shielded Metal Arc Welding), is defined as the process in which two metals are joined by a localized fusion, produced by an electric arc between a metallic electrode and the base metal that is want to unite

Arc welding has been known since the end of the last century. At that time, an uncovered metal rod was used as a filler metal. It was soon discovered that the oxygen and nitrogen in the atmosphere caused fragility and pores in the welded metal, so the metal core was added with a coating that, when burned, was gasified, acting as a protective atmosphere, at the same time contributing to significantly improve other aspects of the process.

In the training of important future engineers, experimentation with some of the manufacturing processes of wide use in the industry is very important, since it allows the students a greater understanding of the processes that they will possibly control in the production of goods or generation. of services.
