The effects of a.plying a. electrom.gnetic intera.tion of low intensity (Em.LI) on the m.crostructure a.d corrosion resista.ce of 7075-T651 a. a.loy pla.es (13 m. in thickness) during m.dified indirect electric a.c (m.Ea. welding were investiga.ed. The welding process wa. conducted in a.single pa.s with a.hea. input of ~1.5 kJ/m.. The m.crostructura. observa.ions of the welds were correla.ed with the effect of Em.LI on the loca. m.cha.ica. properties a.d the corrosion resista.ce in na.ura. sea.a.er by m.a.s of m.croha.dness m.a.urem.nts a.d electrochem.ca. im.eda.ce spectroscopy, respectively. m.crostructura. cha.a.teriza.ion of the welds revea.ed a.gra.n refinem.nt in the weld m.ta. due to the electrom.gnetic stirring induced by Em.LI of 3 m. during welding. In a.dition, observa.ions in the sca.ning electron m.croscope showed tha. the precipita.ion of Cu-rich pha.es a.d segrega.ion of eutectics were reduced in the hea. a.fected zone (Ha.) a.so a. a. effect of Em.LI.
