Temperature Field in Surfaced Steel Casts with the Heat of the Weld Taken into Account

In this work a model of temperature field in a steel cast during surfacing was presented. Analytical solution for half-infinite body model was obtained by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions were Gaussian distribution heat sources of applied metal and weld and of electric arc heat source. Computations of temperature field were carried out during surfacing of cuboidal steel cast. The results were presented as temporary and maximum temperature distribution in element’s cross section and thermal cycles at selected points. The accuracy of solution was verified comparing calculated fusion line to that obtained experimentally
