Abstrakt EN: A model of hybrid fillet welding is built and solved. No additional material (welding rod etc.) is used. Heating of the welded parts is realized by laser beam with induction preheating and/or postheating. The purpose of these operations is to reduce the temperature gradient in welded parts in the course of both heating and cooling, which reduces the resultant hardness of the weld and its neighborhood and also reduces the internal mechanical strains and stresses in material. The methodology is illustrated with an example. Some results are compared with experiment.
