Temperature changes in material during welding can be registered or described in different ways: analytically, numerically or experimentally. For the analytical method, it is necessary to describe a problem by partial differential equations, the solving of which is often difficult or impossible. For the experimental results, it is necessary to have a set of specified equipment and to make one or more expensive measurements. The desired results can be obtained numerically, by using some commercial software packages or by creating one’s own software for a specific problem. All the software is based on a space and time discretization, using finite elements, finite volumes, finite difference method, or their combination. In this paper a comparison of the results obtained by the finite elements method and finite volume method was made on an example of one-dimensional transient heat conduction, the simplicity of which does not distort the generality of the obtained results and derived conclusions.
