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