What part of the beam power is spent on evaporation during keyhole laser welding? How to prove it?

According to the estimates only about 1 percent of the beam power is expended on evaporation (up to 60 % is expended on thermal conductivity and about 40% on melting). On the other hand, there are...

Laser welding simulation - physical or surrogate model? Why the surrogate model is masked as a physical one in reality?

To interpret the hydrodynamics of deep penetration welding, an evaporative model is usually used, taking into account the melt flow resulting from the action of high-pressure steam. However, the...
