Abstract
Analysis of geometry dependencies of bead shaping was carried out at full-scale modelling of technologically possible cross-sections of beads deposited on narrow substrate of 0.5-5.0 mm thickness. The tasks were specified for technological regulation of shape of single-layer bead and series of process criteria was stated, namely efficient rising of narrow substrate being deposited, optimum effective cross-section of the bead and acceptable side machining allowances. Proposed are the formulae for estimation engineering calculations determining the relationship between required height of deposited layer, bead size, mass of deposited metal and filler consumption. 16 Ref., 3 Tables, 9 Figures.
 
Keywords: microplasma powder cladding, nickel heat-resistant alloy, narrow substrate, full-scale modelling of bead cross-section, process criteria of bead shape
