Possibility of use of draught of wire is shownfor quality control of metal compounds without lack of fusion by electrocontact welding of the wire (EWW) by inclined electrodes. It is established that the welding of details by inclined electrodes is performed in the presence of the tangential force leading to emergence of tangential tensions in the contact zone of the metals to be joined. It is shown that tangential tensions promotes activation of contact surfaces, acceleration of formation of physical contact of metals in a zone of their connection, and also promotes crushing and carrying out of oxide films out of limits of a zone of contact of metals by improving the conditions of plastic flow in thin near-surface layers of metal. The reasons for reducing the minimum draught of wire necessary for receiving compound of metals without lackof fusion by EWW by inclined electrodesas compared towelding by vertical electrode
