The paper presents laboratory tests results of wear in the abrasive mass of cultivator coulters subjected to
coated electrode pad welding. In the first stage of the test, one type of electrode was used and a padding weld
was applied to the coulter surface in three different shape variants (perpendicular, parallel to the abrasive mass
stream and V-shaped). The lowest abrasive wear was obtained for samples with a padding weld deposited
perpendicularly to the abrasive mass stream. Therefore, in the second stage of the research, this padding
weld shape was selected and made using three different electrodes. Tests of abrasive wear both in the first
and the second stage of the experiment were carried out at a distance of 100 km by the "rotating bowl unit"
method. Both the direction of the application of the padding weld (shape) and the chemical composition of the
electrode used in the pad welding process significantly increased the resistance to abrasive wear compared to
coulters whose surface has not been welded.
