The welding process is represented by the energy conservation equation where the moving electrode is incorporated considering an oval shaped Gaussian heat source. The governing equation is solved based on the Green function solution and subsequently considered the effect of heat in the weld pool and convection after welding. The prediction agrees well with the experiments and it was found that an oval shape is a better approximation for the heat sourceTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
