Friction stir welding (LAMEF/UGS)

LAMEF is the Physical Metallurgy Laboratory in Brazil.



We are part of the Metallurgy Department, School of Engineering, Federal University of Rio Grande do Sul (UFRGS), Brazil. We have four professors, thirty engineers and one technician who together with PhD students, Masters and undergraduates compose a workgroup of around 200 people in different areas of expertise. We have an impressive infrastructure for the characterization of engineering materials, as well as performing mechanical tests in air and in corrosive media, numerical simulation (finite element) and non-destructive tests.
