Abstract [en]

The paper focuses on the problem of obtaining accurate thermal fields despite the uncertainty of the thermal heat input and thermal properties at high temperatures. The net heat input is the primary factor for obtaining an accurate temperature field. A good correlation between simulations and experiments is obtained. The net heat input during laser welding a bead on a thin plate made of austenitic stainless steel is determined using a water calorimeter. Transient temperature is measured by thermocouples. The FEM is used in the numerical simulation of the process
