Abstract
The mechanical properties, microstructural informations and fracture charac teristics of spot and flash butt welded specimens of two low carbon (0.04 - 0-05%C) niobium (0.05% Nb and 0.15%Nb) microalloyed HSLA steels have been studied in the present Investigation. The tensile strength of the flash but t - welded steel sheets were found to he better than those of the spot weld ed sheets. The hardness profiles and the fracture characteristics of the we ldments were influenced by the microstructural transformations and bonding mechanisms.
