  • Device for detecting seam between abutting workpieces by electron beam
    Patent number: 4400609
    Abstract: A device, for tracking a seam between abutting workpieces by a scanning electron beam, includes a scanning electron beam generating source, a power supply source of the scanning electron beam generating source, at least one secondary emission detector accommodated within a shield and positioned during welding between the scanning electron beam generating source and a workpiece being welded. The detector has an aperture for the scanning electron beam to pass through, and a tap to which is connected a generator of information signals indicative a variation in the surface of the workpiece being welded. This information signal generator is constructed as a differential unit having one input connected to the detector tap, and the other input connected to the power supply source of the scanning electron beam generating source.
