Caracterizações microestruturais e avaliações das propriedades mecânicas das juntas em aço inoxidável AISI 301 L soldadas por MIG e submetidas ao reparo pelo processo TIG
Abstract:The welding has great importance in manufacture of subway cars because it is used in the manufacture of structural components and finishing in passenger cars which are mostly stainless steel. Joints may show the presence of discontinuities. The discontinuities are interruptions that affect the mechanical and metallurgical properties of the weld. The presence of these discontinuities, depending on their size, nature or the combined effect may lead to failure of the weld either by reduction of mechanical propert… Show more
