摘要

FIELD: mechanical engineering; welding production. ^ SUBSTANCE: the invention is pertaining to the field of mechanical engineering, in particular, to the welding production, mainly to manufacture and repair of the executive devices of agricultural machines. The technical effect of the invention is the increased service life of the executive devices of agricultural machines due to improvement of their strength characteristics and a wear-resistance to an abrasive wear. At short-time action on a component of a high intensity current - up to 16 kA in the welding machine MT-1614, as a result of a high heating appear the structural alterations caused by formation of quenching structures. Therefore the strength of the contact patch i.e. the heat-affected zone becomes considerably higher, then the strength of the parent metal. New in the given method is that for strengthening and as a consequence of it for increasing the agricultural machines executive devices components wear-resistance to the abrasive wear was usage of the electric welder -1614. As a result of application of this method there is no need in the further machining or buying the dear alloying materials. ^ EFFECT: the invention ensures an increased wear-resistance of the agricultural machines executive devices components to the abrasive wear due to usage of the electric welder -1614.
