Abstract

This articles describes and outlines the methodology of solving numerical welding simulations and the implementation of validation experiments used to check the results of simulations and removal of errors in selected input parameters.
Examples of experiments are shown to illustrate data as for example temperature cycles,deformations in selected spots,estimation of the size of the melting zone and HAZ,hardness etc.
The obtained results in real experiments in different applications sectors have been applied for calibration of numerical simulation and the achieved simulation results match well with real products.
With such an approach and defined parameters,the verified and confirmed numerical simulation is fully credible and enables to obtain valuable data that can improve manufacturing even of complex assemblies.
