Study of the stability of electrode metal melting and transfer in the process of consumable electrode welding powered by supplies with differing dynamic characteristics

Mathematical Formula to Determine Geometrical Dimensions of Electrode Metal Droplets Transferred with Short Circuits

“…Bardeen [12][13][14], R. Slazak [15], J. Slania [15], Yu.N. Sarayev [16,17], E.A. Zernin [18,19], C.T.…”

“…It was proved in [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] that to ensure stability of arc combustion it is necessary to reduce the size of transferred electrode metal droplets. Estimation of geometric dimensions of the transferred droplets based on output dynamic characteristics of power sources will make it possible to predetermine operational properties of welded structures.…”

Influence of the Cobalt Additive on the Flux Cored Wire of System Fe-C-Si-Mn-Cr-Ni-Mo-V

“…That is why developing materials and innovation technologies of recovering, that greatly increase wear resistance of the items, is an actual purpose today. For this reason, is conducted the manufacturing and development of the special surfacing cored wires [3][4][5][6][7][8]. Due to optimal selection of the chemical composition, deposited coatings exhibit high level of hardness, abrasive and abrasive-shock wear resistance.…”

“…It is founded that the changing the extent of alloying the flux cored wire system Fe-C-Si-Mn-Cr-Ni-Mo-V almost didn't influence on its deposited metal filthy level by non-metallic inclusions. Assessing the influence of the flux cored wires with chemical composition system Fe-C-Si-Mn-Cr-Ni-Mo-V on wear and hardness of the deposited layer was carried out by means of multivariate correlation analysis, which allows to study the patterns of change in the resulting index, which depends on the behavior of various factors, the procedures set forth in the works [6][7][8].…”
