Capturing the temperature gradients of GMAW hardfacing processes by employing CFD and FEM simulation procedures

Hardfacing is carried out whenever a local improvement of the mechanical properties metallic parts demanded. In this regard, gas metal arc welding technology one most popular choices. One decisive factor welded joint quality governed by heat affected zone. The present paper proposes simulation methodology that can be employed for capturing temperature gradients in any location base metal, when such information required. model was developed using ANSYS Workbench software and based on coupled CFD Transient Thermal analysis. first stage, sample subjected to 3D scanning recreating its constitutive surfaces CAD environment. next convective transfer occurring due velocity shielding captured means Experimentally derived temperatures are developing transient thermal analysis, having defined exterior coefficient. last results verified an arbitrary located outside
