Enhancing the Welding-Technological Properties of Electrodes through a Nanostructured Activating Component
Corresponding author: Kamel Touileb
Abstract
This study aims to investigate the effect of the special activating component A-815 on the welding and technological properties of a welding electrode when incorporated into the coating of a rutile welding electrode. This study introduces a novel synthesis method for Nanostructured Functional Ceramic (NFC) (A-815) using pulsed radiation activation. The coating additive significantly enhanced arc stability and deposition efficiency while reducing metal spatter and waste. The results showed the beneficial effect of doping the electrode with A-815 on the welding technological properties. The breaking length of the electrode arc increased by up to 10%, reducing the height of the visor at the end of the electrode by more than 33% and the coefficient of loss due to burnout and spattering by up to 12%. At the same time, the melting and surfacing coefficients were improved, since they increased by 17% when up to 16% of the activator was added. The molten metal losses of the electrode due to spattering and evaporation were significantly reduced.
