Calculation of the thermal cycles of points in automatic welding and surfacing taking special features of melting of parent metal into account
Authors:E A Donchenko
Affiliation:Admiral Ushakov Maritime State Academy , Novorossisk , Russia
Abstract:It is shown that the well-known equations proposed by N.N. Rykalin for calculating temperatures and also the main parameters of the thermal cycles of points in automatic welding and surfacing with the allowance made for the factors associated with the melting of parent metal should be corrected.
Keywords:thermal cycle parameters  peak temperature  fusion  heat  overheat  coefficient of thermal efficiency  fusion area  heat-affected area  instantaneous rate of cooling
