“…Sapozhkov et al suggest varying the production process of MMA welding electrodes via adding nanopowder Ti, Zr, and Cs to electrode components through liquid glass. These additives support arcing stability, improve strength of a weld joint, and, as a consequence, increase the quality of a weld joint and the structure on the whole [12]. There is not much information published on the use of nanostructured materials in welding production.…”

The present work aimed to develop a new coated electrode weld based on ceramic materials. Photocatalysts of nanostructured functional ceramics (PNFCs) were synthesized by means of concentrated solar radiation on ceramic materials. This new process allows the efficient conversion of the energy of the primary source into pulsed radiation, through the adjustable and judicious choice of parameters. The photocatalysts also showed high activity when they were introduced into an electrode coating. The main problem is the complexity of the production of NFC photocatalysts on an industrial scale. A new method was developed for producing ZB-1-grade NFC catalysts using conventional technology, with subsequent activation via pulsed radiation generated by functional ceramics. The results of the addition of NFC photocatalysts obtained using this technology on the welding and technological properties of welding electrodes of the MR-3 brand are presented. The introduction of 1% to 8% NFC of the ZB-1 grade into the coating enhanced the stability of arc burning (Lbla) and increased the diameter of the weld point (ødp.). Moreover, the addition of 1% to 8% NFC of the ZB-1 brand into the coating contributed to a reduction in the losses factor for waste and splashing of electrode metal (ψ) leading to a reduction in the height of the visor at the end of the electrode (hk).

“…nano-powders are used for this purpose (Chekanova, 2015;Il'yashenko & Makarov, 2016). Different methods to introduce modifying powders into a weld metal are suggested (Krushenko & Fil'kov, 2007;Wang et al, 2008;Sapozhkov & Burakova, 2016;Sokolov et al, 2011) -spraying in a shielding gas (Kuznetsov & Zernin, 2012), in a fluxing agent via dipping an electrode into a mixture of ultra-disperse materials etc. Introduction of ultra-disperse powder into liquid glass when manufacturing electrodes is the most efficient method.…”

Growth of the volumes of dangerous and critical welded metal structures constructed under low temperatures imposes additional requirements on the mechanical properties of the weld joints, particularly, on the impact resistance of the weld joint and on the stability of its values. It can be achieved by using coated electrodes with ultradisperse powders of alloying elements in the coating. To develop new improved welding materials we need to optimize the systems of weld metal alloying to meet the increasingly stringent requirements to the welding-operational characteristics. Introduction of a complex ultradisperse powder (Al2O3, SiO2, TiO2, Ni) into the electrode coating applied for manual metal-arc welding ensures more stable process of electrode metal fusing and its transfer into the welding bath, improves the performance characteristics of the welded metal.
