The results of investigations of the effect of the amount and composition of the exothermic mixture in the filler of the powder strips, produced with different rolling parameters, on the melting parameters and the transition of alloying elements from the powder strip to the deposited metal are presented. © 2016 Taylor & Francis

The results of mathematical modelling of the process of propagation of heat in the parent metal in submerged-arc surfacing with a composite strip electrode are presented. The mathematical model was constructed by solving the differential equation of heat conductivity by the finite element method. The calculations and plotting of the graphs were carried out using the MSC Patran software. The model was used to determine the main parameters of the composite strip electrode influencing the shape and dimensions of the pool and the non-uniformity of penetration. The comparison of the calculated and experimental data shows that they are in good agreement. © 2015, © 2014 Taylor & Francis.
