Hello experts,
I've tried to cut a project using SUS304 2B, but unfortunately the dross formation is rather critical and the dross formation. I've increase the focus distance but the result almost the same.
Hi Abdul Fattah,
Your question does not contain necessary information on the process (sheet thickness, laser type and operation mode, cutting speed, assist gas type/pressure, nozzle type/standoff etc.) so the true answer can be hardly made.
Typically the problem of dross for chromium steels is solved by using neutral gas with high pressure (for example nitrogen at 25 - 30 Bar)
Hello Dr Yurevich,
My mistake, forgot to attach information on the processing parameters.
Material : SUS304 2B
Thickness : 3mm
Laser type : CO2
Operation mode : CW
Laser power : 2800 W
Cutting speed : 1000mm/min
Assist gas type : N2
Gas pressure : 6.5 bar
Nozzle gap : 0.5mm
Ive tried using higher pressure assisted gas and the problem solved. Thank for your advice.
