FIELD: agriculture.
SUBSTANCE: method may be used to manufacture lancet points of tillage tools. When manufacturing welded point, wings are welded to form V-shaped edge at the side opposite to welded seam, with length of 30-70 mm with opening angle of 30-55°, and it is filled with filler charge. In stamped point U-shaped groove is formed along axis of symmetry on outer side of nose portion, with length of 15-30 mm, and filler charge is placed in it. Induction welding is carried out with simultaneous heating of point wings for tempering provided that hardness of welded metal by 2-8 units according to HRC compared to the main metal.
EFFECT: method provides for increased wear resistance of lancet point nose part and reduction of its tractive resistance in soil.
