Abstract
A surfacing method comprises feeding alloying material to the weld pool in between two consumable electrodes, with the distance between those electrodes being determined depending on the diameter of the electrodes, feed mass velocity of the alloying material and the total feed mass velocity of the electrodes. An apparatus for controlling the surfacing process according to the proposed method includes an electrode feed rate transducer connected to series-coupled converters, one of which converters determines the ratio of the amount of the alloying material to the total amount of metal being fed to the weld pool, and the other one determines the alloying degree of the surface layer being formed. The converters are connected to an adder unit connected to a device for delivering additional alloying material whereas the converter for determining the alloying degree includes a programmer device and is connected with the device for feeding the alloying material.
