Effect of boundary conditions and heat source distribution on temperature distribution in friction stir welding

Primary tabs

Simar, Aude [UCL] Lecomte-Beckers, J Pardoen, Thomas [UCL] de Meester, B.

Welding experiments on Al-6005A have been carried out using a fully instrumented milling machine. The power input was calculated from the measured torque and forces. The thermal cycles were measured at various locations close to the weld centreline. A finite element pseudo-steady-state uncoupled thermal model was developed, taking into account the influence of the welding parameters on the power input. The distribution of the total power input between surface and volume heat sources was also studied. The measured and predicted thermal cycles are in good agreement when proper contact conditions between the workpiece and the backing plate are introduced.
