The aim of this study was to research the impact of the overlaying to increase the resistance to the abrasive wear of the ploughshare using three types of welding tubular wire electrodes. These tubular wire electrodes are used to increase the active parts of machines and equipments processing the soil. The experiment was performed on the six ploughshare plough, where the first and last share was without the overlay. Overlaid shares were compared with non-overlaid shares as standards. From evaluation, it is clear that the best overlaying materials are FILARC PZ 6159, OK Tubrodur 14.70 and OK Tubrodur 15.82. The results proved that the wear of the ploughshare is increased towards the heel. The study determined the weight loss during the ploughing and ploughshares dimensional width. The research results did not confirm the benefit of the overlaying with regard to the ploughshare lifetime.Keywords:
