In this work we report the phase structures of the EL-Hard padding weld layers and their effect on their abrasive wear resistance. The application of light and electron scanning microscopy examinations revealed subtle differences in the structures of the padding welds which affect their strength and usable properties. Abrasive wear resistance tests utilizing a “spinning bowl” method performed in real soil masses and hardness tests showed a close relationship between the abrasive wear resistance values and chemical composition of the tested padding welds. The obtained results are explained by the presence of the carbide - forming elements such as B, Cr, Mo, Nb, V and W in the chemical composition and types of the carbide phases present in the structures of the EL-Hard padding welds.
