Abstract
This paper presents the results of evaluation of the influence of complex-alloyed powders (CAP) on welding-technological properties of flux-cored wires and deposited metal performance. Possibility of ensuring a high degree of flux-cored wire alloying at reduction of its diameter is considered. Tribotechnical characteristics of metal deposited with flux-cored wires are determined at CAP application as a filler. The paper presents the results of metallographic investigations of deposited metal. It is established that CAP application as flux-cored wire core is favourable for the mode of electrode metal melting and transfer leading to improvement of their welding-technological characteristics. Wear resistance studies of deposited metal showed an improvement of wear resistance of deposited metal operating under the conditions of abrasive wear and metal-over-metal friction. 4 Ref. 5 Tables. 3 Figures.
