Abstract
The paper presents the characterization of basic types of welding power heat sources used in the analysis of temperature field. The first part of the paper contains the genesis of heat source models used for welding processes. It describes mainly the flat disk and double-ellipsoid Goldak models. The second part of the paper presents as an example numerical (FEM) models of welding heat sources. Four types of disk, double-elispsoid, cuboid and hybrid models were constructed. The results of temperature field obtained from these models were presented and analyzed in comparison to each other. The results of temperature distribution show that it is very important to select adequate type of heat source model for the simulation of a welding process.

Modele spawalniczych źródeł ciepła w analizie pola temperatury
W pracy przedstawiono charakterystykę podstawowych rodzajów modeli spawalniczych źródeł ciepła wykorzystywanych w analizie pola temperatury. Pierwsza część pracy obejmuje genezę modeli źródeł ciepła przy spawaniu oraz opis takich modeli jak model płaski dyskowy, oraz model podwójnie elipsoidalny Goldaka. W dalszej części pracy przedstawiono przykłady zbudowanych modeli numerycznych spawanych płyt, w których zaimplementowano cztery różne modele źródeł ciepła: dyskowy, podwójnie elipsoidalny, prostopadłościenny i hybrydowy. Zobrazowano wyniki obliczeń numerycznych (MES) w postaci rozkładów pola temperatury w analizowanych modelach oraz dokonano porównania otrzymanych wyników.
