Özet

Tensile shear stresses and microstructure of dual steels with different volume fractions of martensite are studied after spot resistance welding. A Mn-Ni low-carbon steel heated in the intercritical temperature range and cooled in water and in air is studied. Spot resistance welding of test pieces is performed for different times at constant welding pressure and peak value of the welding current. The microstructure of the welded specimens is investigated and their permissible tensile shear stresses are determined.
