Hand guided device for laser welding of a workpiece, has optical sensor for laser focus point position and a control unit for triggering interrupt of laser

摘要

The device (1) has a sensor (6) for optically detecting the distance from the workpiece (2). A control unit detects an unwanted operating condition based on the sensor output. The control unit triggers a signal to interrupt the laser beam (5) when the sensor detects that the focus point lies outside an ideal area.
