Title: Sensitivity Analysis of the Thermal Task at Electric Arc Welding
Keywords: welding, modeling, thermal task, sensitivity analysis

Abstract: Sensitivity analysis is a specific step during simulation modelling of processes related to heating and cooling of the welded structure. It is necessary due to the fact that in most cases the data on the thermal properties of the material are not known for the whole studied temperature range. This report examines the impact of the uncertainty of these characteristics on the case of submerged arc welding. An analysis is made of the impact of the mesh size on the results obtained also.
