Název v původním jazyce

Improvement of model of aluminium alloys behaviour for application in numerical simulations of welding

Popis výsledku v původním jazyce

This article describes how to modify numerical solutions to enable more accurate prediction of the size of heat affected zones (HAZ) during welding of heat treatable aluminium alloys. The size of HAZ affects properties of a weld joint, such as e.g. hardness and strength, and it is also a factor on residual stress and deformation after welding depends. Welding experiments were performed using material EN AW-6082 to obtain input data for numerical simulations. Calibration thermo-metallurgical numerical analyses were performed using simulation software Sysweld, where data from the standard Sysweld material database were used. Subsequently, based on information from literature and data obtained during welding experiments, some changes of parameters in Leblonds formula (which describes metallurgical transformation in HAZ) were done. The results obtained with modified material database show that it is possible to perform numerical simulations of aluminium welding with significantly more accurate prediction of the size of the HAZ.
