In recent years use of Zr-Nb alloy has increased in nuclear and chemical industry due to its corrosion resistance and enhanced strength compared to tin based zirconium alloys. To select suitable welding parameters to achieve quality weld, understanding of temperature and velocity fields during process in fusion zone and heat affected zone are essential [1, 2]. The non-linear relationship between the laser welding process parameters and welding bead geometry is complicated. The laser welding process parameters determined by trial and error methods demand many numerical and experimental simulations, which will be expensive and sometimes may not yield fruitful results. Satyanarayana et al.  have devel- oped a generic model using Fluent ANSYS V16.0 with VC++ code and demonstrated its validity by considering the test
