This paper describes the method of shaping the product using 3D technology by means of applying arc heating and consumable material – a wire with a diameter of 1.2 mm. The aim of the work is to study the structure and mechanical properties of the product manufactured using additive 3D technology. Each deposited layer consists of three separate beads: two lateral ones, which provide the set contours of the layer, and one middle one, which fills the space between the two lateral ones. Electric arc surfacing was carried out with the help of a welding robot. The use of a robot made it possible to control the time between layer depositions, thereby controlling grain growth. Also, the use of a robot makes it possible to reproduce a set part as accurately as possible according to a pre-calculated and designed model with a minimum error of repetition of the torch movement of ±0.03 mm. As a result, the structure and mechanical properties of the deposited product were investigated. It is shown that the product manufactured according to the presented technology has a fine-grained ferrite-pearlite structure; the grain size ranges from 7 to 10 numbers. The mechanical properties along and across the deposited layers were studied. The indices practically do not differ. A comparison of their values with normative ones showed that they exceeded normative values by 10–50%. 14 Ref., 3 Tabl., 4 Fig.
