"Welding is a special process, that is carried out in a very short time interval with a small melting area and non-linear dependences. Consequently it is rather difficult to describe this process. The computations of temperature fields are based on thermal-physical data given by the Fourier differential equation and on the temperature dependence of the coefficient of the heat transfer into the environment. The heat transfer coefficient is an example of how difficult it is to acquire quality input data for simulation computation. It changes depending on the type of plane: vertical, horizontal or inclined angle-wise. It also matters if it is an upper surface of a plate or a lower surface of a plate, because the difference can be up to 30%. Simulations in the Sysweld programme will show how different types of the coefficient of heat transfer into the environment can influence the overall simulation computation result." . . . . . .
