Abstract
A laser welding, monitoring system comprising a laser welding beam energy source and means for directing laser beam energy from said source and on to a concentrated laser weld spot on the workpiece to be welded shaped or cut by laser energy. A laser probe source is arranged to direct light from said probe source on to the workpiece. Laser beam detector means is arranged to pick up and monitor reflected light originating from said laser probe source and reflected back from the workpiece, wherein the light from said probe source is directed in a peripheral path encircling said concentrated laser weld spot.
