Abstract: On the basis of studying LD10CS aluminum alloy gas tungsten-arc welding (GTAW) with longitudinal magnetic field controlling, the mathematics model of weld pool is built up. Fluid flow and heat transfer of the weld pool is analyzed on in the spot GTA welding with longitudinal magnetic controlling. The model can be applied to analyze the fluid flow and heat transfer phenomena on this welding process. The analytical results are in good agreement with the published experiment measurements.

Key words: Longitudinal magnetic  Weld pool  Fluid flow  Numerical analysis
