摘要： A method for quality inspection of laser material processing includes performing laser material processing on a workpiece and generating, by a sensor, raw image data of secondary emissions during the laser material processing of the workpiece. The method also includes determining a quality of the laser material processing by analyzing the raw image data of the secondary emissions.

摘要： A laser system includes a controller, a laser source, a laser scanner, and a laser containment apparatus. The laser containment apparatus includes a mounting structure for the laser scanner, a shroud assembly coupled to the mounting structure, and a seal interface coupled to the shroud assembly at an opposite end from the laser scanner. The shroud assembly surrounds a working volume of the laser scanner and includes a vacuum port connected to a vacuum source and a purge port that guides purge gas from a purge gas source toward the laser scanner. A distal end of the seal interface is formed of a pliable material that compresses to seal the shroud assembly to a target surface of a workpiece upon establishment of a negative pressure differential between a vacuum pressure inside the shroud assembly and ambient atmospheric pressure.
