Abstract

This paper addresses the FEM numerical analysis of thermal field distribution in a thin-walled aluminum alloy pipe subjected to circumferential welding with a laser beam as a source of heat. The paper presents constitutive equations describing the studied phenomenon. Computation results were compared to the experimental welding results. Welding process was performed on the TRUMPF CO2 laser, model TruFlow6000. The temperature ahead of the moving laser beam front was measured by the optical pyrometer. Pyrometer indications confirm that there is a sufficient level of correspondence between the numerical analysis and the actual results.
