Air cutting revisited
Oxygen and nitrogen, two standard assist gases used in laser cutting, create two different reactions at the laser head. Oxygen produces an exothermic reaction, and the laser burns the metal. Nitrogen fosters a melting process, and the laser heats the metal without a chemical reaction, with... Read more...
