摘要

The holding device for a welding part in frame of a welding process by a protective gas welding arrangement having a gas nozzle, for removing a broken or damaged threaded bolt from a base component, comprises holding means (4) on its side turned away the gas nozzle for the welding part, a socket (7) having a longitudinal slit (6), where two claw-like passing shanks (9, 10) are connected to the socket in longitudinal direction. The holding device is fixably arranged on the gas nozzle of the protective gas welding arrangement. The holding device for a welding part in frame of a welding process by a protective gas welding arrangement having a gas nozzle, for removing a broken or damaged threaded bolt from a base component, comprises holding means (4) on its side turned away the gas nozzle for the welding part, a socket (7) having a longitudinal slit (6), where two claw-like passing shanks (9, 10) are connected to the socket in longitudinal direction. The holding device is fixably arranged on the gas nozzle of the protective gas welding arrangement. The holding means are arranged to the end of the shank for the reception of the welding part. The interior diameter of the socket is formed against the external diameter of the gas nozzle. The ends of the shank are equipped on its side turned to the welding part with a form that corresponds to the external arrangement of the welding part. The form is arranged as two flat elements (14, 15) arranged to each other. The form is formed as arc-shaped flat element. The holding means are arranged against the flat elements of the form as spherical segment, cone or pyramid. The ball segments are formed as a hemisphere.
