description: The given work is devoted to studying mathematical models of heat sources as applied to beam processing. The research set the following goals: 1. Study of modeling features for laser processing processes. 2. Identification of the distinctive characteristics of the classical model of the thermal field of Rosenthal and Rykalin. 3. Research mathematical model of the thermal field of Goldak. 4. Analysis of Goldak model extensions for laser and laser-arc welding. As a result, various models of heat sources were analyzed. Calculations were made on the distribution of heat at some point in time. From performed analysis it can be observed that two heat sources in hybrid welding process are cooperating in a single welding pool. Changing the distance between heat sources changes the nature of material melting and for distance d=8mm heat sources there is no interaction between heat sources. In this case the process proceeds as two separate welding methods. Laser beam heat source determines the weld penetration depth (Fig. 8), whereas the geometry of the weld at the top surface mainly depends on the arc heat source. As shown in this figure, the calculated geometry of the weld and heat affected zone agrees well with experimental results. The developed mathematical models and numerical solutions can be used to analyze the impact of important process parameters on the quality of laser-arc hybrid welded joints.
