摘要： The invention relates to a machine for material processing by way of a laser beam, in particular for laser beam welding, comprising a machine-guided protective housing having an outlet opening, which surrounds the laser beam directed onto a workpiece during the material processing. In order to create a machine for laser beam welding, which allows better personal safety without completely enclosing the machine, it is proposed that the protective housing be assigned at least one sensor which senses particular chemical or physical properties as measured variables, the sensor is connected to a controller which compares the sensed actual values of the measured variables with a setpoint value for the measured variables and, depending on the setpoint/actual value comparison, interrupts the laser beam and/or prevents the activation thereof. Furthermore, a method and an arrangement for improving personal safety during the operation of such a machine are specified.
