摘要
Theoretical modelling of the plasma plume induced during welding of iron sheets with CO2 laser are presented. The set of equations consists of equation of conservation of mass, energy, momentum and the diffusion equation and is solved with the use of commercially available program Fluent 6.2. The computations are made for the cases when the shielding gas is either argon or helium. The results show that in the case when argon is the shielding gas there are actually two plasmas; argon plasma and metal plasma.
