The effects of a.pl.ing a. el.ctroma.netic intera.tion of l.w intensity (EMIl.) on the microstructure a.d corrosion resista.ce of 7075-T651 a.0}a.0}oy pl.tes (13 mm in thickness) during modified indirect el.ctric a.c (MIEa. wel.ing were investiga.ed. The wel.ing process wa. conducted in a.singl. pa.s with a.hea. input of ~1.5 kJ/mm.
