  • Method of laser cutting metal workpieces
    Patent number: 6060687
    Abstract: The invention concerns a method for laser cutting metal workpieces which contain bound oxygen by using a mixture of ay least one inert gas and hydrogen as the cutting gas. The hydrogen protein of the cutting gas prevents oxygen which is from the metal during the cutting process from causing undesired oxidation in the region of the cutting point. The formation of burrs and furrows is thus prevented.
