LaserWelding: avoiding Temperatures > 3500°C / Temperature break

with my modell i am simulating a process comparable to laser welding.
Depending on the track energy, that i use, keyhole effects can occur. (in the real process)
Me, i am not interested in simulating keyhole effects and i just want to simulate some kind of conduction mode welding with marangoni effects.
When i simulate high track energies, it is possible that the temperatures in the centre of the melt pool reach unrealistic values. (> 10,000 K)
How can i implement some kind of temperature break, if the choosen track energy is too high to avoid temperatures above 3500 K?
I tried to implement some kind of negative source that takes the energy out of the system when the temperature reached the defined temperature threshold. if(T[1/K]>3500, 10e15[W/m³],0[W/m³]) (something like this ...)
Does anybody know a more elegant solution?
Thank you very much
Michael
