Abstract
Rotating pistol or welding by electronic bombardment consists of an electronic barrel, a secondary vacuum chamber around it and a primary vacuum chamber in the zone of the joint to be welded. It is centred on the joint by a chuck and can turn by ball bearings. The barrel support has a hole through which the electron beam passes and this may be closed by a sliding shut-off sealed by a joint so that the secondary chamber and the barrel may be kept under vacuum when the lower chamber containing the joint is open to the air, thus decreasing the welding time since only a small chamber has to be evacuated each time.
