Beschreibung
Zusammenfassung:	FIELD: welding processes and equipment, namely methods for making and restoring plowshares of agricultural machines. ^ SUBSTANCE: method comprises steps of surfacing on working surface mean- and high-carbon steel plowshare of low-carbon electrode material in the form of mutually parallel beads; forming each successive bead at rate providing formation of quenching structure after cooling of previous bead. ^ EFFECT: increased useful life period of plowshares due to their enhanced strength characteristics and improved resistance against abrasive wear. ^ 1 dwg, 1 ex
