you can stamp numbers too you know.. the real problem is that some pros warned about is cold welding. every method has its own cons
Stamped on a sheet of metal is probably best IMO

To avoid cold welding just lube the washers
Just put a number above. Make those from stainless steel- 1,400 to 1,530 °C melting point

Must number them
